Release notes for Model 204 version 7.5
These release notes list the enhancements and other changes contained in Model 204 version 7.5, which is still in development. Until the commercial release of the software, Rocket reserves the right to add to, remove, or change anything described herein.
Overview
These release notes contain installation and features information for the Rocket Model 204 version 7.5.0 release. Before beginning your installation, please read through this information about product installation and changes.
New in this release
This section summarizes the new features and enhancements for Model 204 version 7.5.0.
SOUL (User Language)
The significantly enhanced, object-oriented, version of User Language is now called SOUL. All existing User Language programs will continue to work under SOUL, so User Language can be considered to be a subset of SOUL, though the name "User Language" is now deprecated.
- Sirius object-oriented language extensions integration
- ECF statements can pass up to 60 parameters
System Management
- Writing records to the SMF data set without an SVC installed
Performance
- GTBL can be stored above the bar
- Support for physical field groups
Operating system requirements
Requirements for Model 204 version 7.5 are still being determined.
Model 204 version 7.4 required the following operating system support:
- For IBM z/OS: Version 1 Release 7 is sufficient for all new functionality except for the following
features:
- Large (1 MB) page support requires Version 1 Release 9.
- Extended address volumes (EAV) requires Version 1 Release 12.
- For IBM z/VM: Version 5 Release 4.0 or later
- For IBM z/VSE:

- Version 4 Release 3 or
- Version 4 Release 2.1 or
- Version 4 Release 2.0, with these program temporary fixes (PTFs) installed:
- UD53436
- UD53437
- UD53438
- UD53439
Hardware requirements
Requirements for Model 204 version 7.5 are still being determined.
Model 204 version 7.4 required the IBM z/890 or above processor, except for the following feature:
The large (1 MB) page support feature requires the IBM z10 or above processor.
Model 204 compatibility with operating systems
Content for version 7.5 is still to be determined.
For information on Model 204 certification with IBM operating systems, see: http://www.rocketsoftware.com/products/rocket-model-204/technical-information
Model 204 compatibility with Connect*
All supported versions of Connect* are compatible with Model 204 version 7.5.0.
However, CLOB/BLOB support requires Connect* version 7.4.0 or higher. Use of Connect* versions earlier than version 7.4.0 to SELECT, UPDATE, or INSERT CLOB/BLOB data will fail and might produce unexpected application behavior and/or return an error.
Connect* version 7.5.0 is compatible with versions of Model 204 that are earlier than version 7.5.0.
SOUL (User Language) enhancements
Much of the substantial new and enhanced functionality described in the following subsections is available as a result of the acquisition of Sirius Software. The functionality that is the subject of the initial subsection, "Object oriented programming," motivates the new name for User Language, SOUL, often thought of as Simple Objective User Language.
Object oriented programming
As of version 7.5 of Model 204 (and backward compatible with existing User Language applications), the SOUL language is equipped with Object-Oriented Programming(sometimes abbreviated OO) capabilities comparable or superior to other contemporary object oriented languages. The OO features were formerly contained in the Janus SOAP User Language Interface, and you can use Object oriented programming in SOUL as an entry point to the extensive SOUL OO documentation. In particular, you might want to begin with the OO tutorial.
Record capacity increase
In this version of Model 204, the record limit is increased from sixteen million records to forty-eight million records per file.
New SOUL statements
Non-OO enhancements in SOUL
- Mixed-case SOUL
- Longstrings
- Unicode
- Double quotation marks for quoted strings
- At sign (@) on right side of assignment
- Is Defined and Is Visible tests
- Copy qualifier for subroutine parameters
- Normal syntax for LOB fields
- Implicit concatenation
- Relative values for Model 204 numeric parameters
- SOUL macro facility
- External Call support for Stringlists and $lists
SOUL support for field groups
ADD (or INSERT or DELETE) FIELDGROUP statements
The ADD FIELDGROUP statement and the INSERT FIELDGROUP statement behavior parallels the behavior of the ADD and INSERT statements for simple fields. The DELETE FIELDGROUP statement handles more situations and is therefore more complex. See Updating field groups for details.
Statements for handling field groups
SOUL now provides several statements for handling field groups:
- FOR FIELDGROUP
- FOR ALL OCCURRENCES OF FIELDGROUP (FAO FIELDGROUP)
- FOR EACH OCCURRENCE OF FIELDGROUP (FEO FIELDGROUP)
See Special statements for multiply occurring fields and field groups for details.
Output statements for field groups
The following SOUL statements provide display output for Model 204 field groups:
AUDIT ALL FIELDGROUP INFORMATION (AAFGI) PRINT ALL FIELDGROUP INFORMATION (PAFGI)
See Output statements for details.
Field group SORT support
You can use field groups in sorted sets. SORT statement support for field groups lets you sort records with field groups as well as reference field groups in the sorted sets. For example, you can issue a FAO FIELDGROUP
statement or FEO FIELDGROUP
statement against the sorted set.
EQ VALUE retrieval condition
User Language now provides the EQ VALUE clause to support expressions in FIND statements.
See Using expressions in FIND statements for details.
EQ WITH retrieval condition for concatenated fields
User Language now provides the EQ WITH clause for retrieving CONCATENATION-OF fields. Model 204 automatically builds the concatenated value.
See Using expressions in FIND statements and EQ with retrieval condition for concatenated fields for details.
External Call Facility (ECF)
EXTERNAL CALL statements can now pass more parameters. The maximum number of parameters that can be passed in an EXTERNAL CALL statement has been increased from 40 to 60. The maximum value setting for ECPSIZE is increased from 1310680 to 1966020 to accommodate the extra parameters.
ECF is available only on z/OS systems. For more information about the External Call Facility and the EXTERNAL CALL statement, see the Rocket Model 204 System Manager's Guide.
REPEAT statement UNTIL option
The REPEAT statement now supports the UNTIL option. In previous releases, only REPEAT WHILE was supported.
A REPEAT UNTIL statement enters the loop body prior to checking the condition.
New and changed classes and methods
New HttpRequest TranslateTable property
The TranslateTable HttpRequest property makes it possible to set the translate table to be used for EBCDIC to ASCII translation of data in an HttpRequest object.
New InvalidTranslateTable class
Objects of the InvalidTranslateTable exception class are thrown when a requested system translate table cannot be found. It is currently thrown only by the TranslateTable HttpRequest property.
New bit manipulation String functions
New bit manipulation functions BitClearString, BitCountString, BitFlipString, BitSetString, and BitValueString make it easier to manipulate the bits in a string.
New InvalidBitNumber class
Objects of the InvalidBitNumber exception class are thrown when an invalid bit number is requested by a bit manipulation function. It is currently thrown only by the BitClearString, BitFlipString, BitSetString, and BitValueString functions.
The Base64Encode=False argument can be used with the LoadFromRecord method to disable any base64 encoding of field values.
Alternatively, the CharacterMap argument (with a non-null value) can be used to disable any base64 encoding of field values, and to specify translations, which can avoid request translation due to X'00' and/or untranslatable characters in field values.
These arguments are also added to the NewFromRecord and ToXmlDoc methods.
New option for AppendJournalData
The QT option is added to the AppendJournalData method, to include QT type audit entries.
New parameter for AddField
The Strip option is added to the Screen class method AddField to allow suppression of leading and trailing blank removal from input fields.
New and changed $functions
Former Sirius $functions
The $functions referred to by the link below are added to SOUL as a result of the acquisition of Sirius Software:
$SNDMAIL attachment ASCII translation
The $SNDMAIL function can now translate an attachment to ASCII before sending it. This translation is useful if the $SNDMAIL attachment is a CLOB (CHARACTER-LARGE-OBJECT) such as a text document.
The $SNDMAIL function now accepts an optional parameter after the name of the attached object. If this parameter is set to 'C' (or to a percent variable with the value 'C'), the object in the buffer is translated to ASCII before being attached to the email.
If this parameter is not specified, the object in the buffer is sent as a binary object.
In this example:
%RC = $SNDMAIL(%SUBJECT,,%BODY,%FROM,%TO,,,,'CLOB.TXT','C')
the CLOB.TXT attachment will be translated to ASCII before being attached to the email.
New function calls for field groups
When a field group is added, a field group ID is assigned to the field group.
- $FIELDGROUPID returns the ID of the current field group.
- $FIELDGROUPOCCURRENCE returns the current occurrence number of the field group.
Sirius products and product enhancements
These products are now available to Model 204 customers as separately purchased items as a result of the acquisition of Sirius Software.
Changes to Janus SSL support
Under Model 204 version 7.5, Janus products:
- Drop support for version 2 of the Secure Sockets Layer encryption protocol (SSL V2)
You can use the SSLPROT parameter on the JANUS DEFINE command for a port to explicitly specify, or limit, the SSL protocols available for a connection. The SSLPROT documentation describes the SSL protocols that Janus supports.
Janus support for SSL V2 also included an option to specify a larger than "legal" input buffer for connections not strictly conforming to the V2 standard. You specify that buffer size with the JANUS DEFINE SSLIBSIZE parameter, and the SSLIBSIZE maximum value as of Model 204 V7.5 is reduced (from 32767 bytes) to the SSL maximum allowed size of 16384.
- Add support for new ciphers and TLS levels
You can use the SSLCIPH JANUS DEFINE parameter to specify the SSL ciphers available for a connection. The SSLCIPH documentation describes the SSL ciphers that Janus supports.
Support for physical field groups
Model 204 supports non-relational, de-normalized data structures. Many Model 204 sites have enjoyed significant cost and performance benefits from efficiently processing multiply occurring fields. This concept has been enhanced to introduce physical field groups that let you view and process groups of fields as a logical entity.
You can define a physical field group only for files with the FILEORG X'100' setting. To take advantage of field groups in files defined before Model 204 version 7.5, you must reorganize the files with a FILEORG setting that includes the X'100' bit.
Files with FILEORG X'100' can have up to 32,000 fields.
For more information, see field group design.
Increased Table B record number capacity
Table B can now contain up to 48M possible record numbers. (The previous limit was 16M.)
Set the FILEORG X'200' bit at file creation time to allow for the increased record numbers.
Notes:
- The limit for BSIZE remains at 16M.
BSIZE * BRECPPG must be less than or equal to 48M (actually decimal 50,331,648 to be exact).
For example, if BSIZE = 16M, BRECPPG cannot be more than 3.
- FILEORG=X'200' cannot be specified for files with hash key or sorted file organization.
Automatic fields
Model 204 now lets you define a field whose value is automatically maintained.
A field can count occurrences of another field so that every store or delete of the field occurrence changes the count in the automatic field. Automatic fields are defined with the following attributes:
- COUNT-OCCURRENCES-OF
- CREATE-TIME
- CREATE-TIMEUTC
- CREATE-USER
- UPDATE-TIME
- UPDATE-TIMEUTC
- UPDATE-USER
The value of an automatic field is updated at the start of a transaction by Model 204 and you cannot set it explicitly by a program. Any valid update statement causes the appropriate time and user stamps to be updated. For example, the time and user stamps will be undated when DELETE FOO(8) is processed, even if there are no occurrences of FOO in the record and an actual update does not take place.
Once you define an automatic value for a field, you cannot redefine the automatic value.
Concatenated fields
Model 204 now lets you define concatenated fields.
Fields that make up concatenated field values must be either AT-MOST-ONE, EXACTLY-ONE, or OCCURS 1 and must all be in the same field group context (or not in a field group). Fields that occur in all field groups (FIELDGROUP *) cannot be used in a concatenation.
If a concatenated field becomes longer than 255 bytes after adding separator and escape characters, the update request is cancelled.
New field attributes
Model 204 version 7.5 introduces the new DEFINE FIELD attributes described in this section. These attributes apply to all fields in Model 204.
Note: These attributes all require that the FILEORG=x'100' parameter be set on the file containing the fields.
Changes in the new field attributes are detected during the redefinition of an existing field. When such a change is detected, the following messages might be issued:
M204.1260: [FIELD | FIELDGROUP] WAS PREVIOUSLY DEFINED WITH DIFFERENT ATTRIBUTES, NEW [FIELD | FIELDGROUP] OPTIONS IGNORED
or
M204.2884: [FIELD WAS PREVIOUSLY DEFINED AS A FIELDGROUP | FIELDGROUP WAS PREVIOUSLY DEFINED AS A FIELD], NEW DEFINITION IGNORED
The table below lists the new field attributes.
Attribute | Abbreviation | Description |
---|---|---|

System management enhancements
Writing records to the SMF data set
Having Model 204 write records to the SMF data set no longer requires the installation of an SVC.
Therefore, the SMFSVC parameter is no longer required and, if present, will be ignored and flagged with the following informational message:
M204.0204: PARAMETER SMFSVC OBSOLETE AND NOT RESET
However, the SMFLORN and SMFSLRN parameters must still be present in CCAIN if SMF records are required.
Performance enhancements
64-bit addressing and Above The Bar (ATB) storage
Model 204 moves above the (2G) bar to increase scalability, performance, and growth potential. With this release of Model 204, 64-bit addressing becomes the de facto standard for all subsequent versions.
In addition to the ATB support for FTBL released with Model 204 version 7.4, version 7.5 adds ATB support for GTBL, NTBL, and QTBL, using the same SERVNSA and SERVNSSZ parameters used for FTBL.
When using non-swappable ATB server space, each user will get SERVNSSZ bytes of ATB space, even if the thread is logged out or running resident requests. For greater efficiency, Model 204 version 7.5 also provides swappable ATB server areas that can supplement or replace the non-swappable areas. These swappable ATB server areas are controlled by the SERVGA and SERVGSZ parameters.
GTBL in above the bar storage
GTBL can now be placed into non-swappable server storage area above the bar. In order to store GTBL in ATB storage:
- Increase the SERVNSSZ parameter by the GTBL size.
- Set the second byte of the SERVNSA parameter to
X’80’
, so the value of SERVNSA isX'00800000'
.
Note:
The settings for each server table above the bar are independent of each other.
So if both FTBL and GTBL are placed above the bar, then SERVNSA should be set to X'02800000'
.
NTBL and QTBL in above the bar storage
Needs details . . .
XmlDoc pages in above the bar buffer pool
With this release, the CCATEMP pages used for XmlDoc objects use the above the bar buffer pool, which may allow the below the bar buffer pool to be reduced, perhaps providing more storage for server areas. It also may provide a reduction in CPU utilization, especially when the TEMPPAGE parameter is used to allocate CCATEMP in memory.
Improved range searching by Ordered Index (OI) chunk
The new CHUNK attribute for the DEFINE FIELD command enables more efficient range searching on Ordered Index numeric (ORDERED NUMERIC) fields. CHUNK improves performance of the "RANGE" and "BETWEEN" FIND terms. The CHUNK field attribute defines a subrange ("OI chunk") of the data range. Searching by OI chunks on a range of data requires fewer scans of the ordered index entries to find the desired data. Once OI chunk fields are defined, they are automatically used by FIND processing, so no application code needs to be changed.
After defining an ORDERED NUMERIC field, you define one or more related OI chunk fields containing data from the original base field rounded down by a specified CHUNK size.
Example:
DEFINE FIELD YYYYMMDD WITH ORDERED NUMERIC DEFINE FIELD YYYYMM WITH ORDERED NUMERIC INVISIBLE CHUNK 100 FOR YYYYMMDD DEFINE FIELD YYYY WITH ORDERED NUMERIC INVISIBLE CHUNK 10000 FOR YYYYMMDD
CHUNK requires FILEORG=x'100' and the INVISIBLE and ORDERED NUMERIC field attributes.
MQ/204 enhancements
Freeing MQ/204 subtasks and associated storage
The new MQDELDTP PST (pseudo subtask) checks for MQ/204 subtasks that are in a delayed detach state. MQDELDTP detaches MQ/204 subtasks that have finished their work and releases their associated storage areas.
Other features
AT-MOST-ONE and field groups
The AT-MOST-ONE attribute is now applicable to a field group definition.
Storing and updating LOBs
All large object data (LOBs) in a FILEORG=X’100’ file are chained. There are four bytes per Table E page overhead for chained LOBs. The pages used by a chained LOB are not contiguous.
Handling LOBs in FILEORG=X’100’ files also has the following effects:
- LOBs can be changed as needed. The RESERVE clause is ignored in a LOB field ADD statement processing, as well as the STORE RECORD statement processing of fieldname=value pairs. Consequently, the CHANGE statement does not fail because of insufficient reserved space. If the CHANGE statement requires that a LOB field be extended, it is.
- The value of the EHIGHPG parameter is always one less than the high water mark of the number of pages used to hold LOBs. (Unless none were ever added, in which case it is zero, not -1).
- The value of the EPGSUSED parameter is always the number of pages currently being used to hold LOBs.
- The COMPACTE command does not process FILEORG=X’100’ files, just as it does not process a file created in V6R1 or earlier. Thus, issuing a COMPACTE command for a FILEORG X’100’ file produces an error message.
- The TABLEE command effectively does a VIEW ESIZE EHIGHPG EPGSUSED for a FILEORG X’100’ file. Consequently there are no TABLEE overhead pages in a FILEORG=X’100’ file.
Constraint attributes
You can set range constraints on fields using the constraint attributes. Each set of range attributes is comprised of four attributes (GE, GT, LE, LT) that you can use to establish a range for integer values, float values, or date-time stamp values. The types of range attributes are mutually exclusive. For example, you cannot define a field with the FLOAT-GE and INTEGER-LE attributes.
If a range constraint is redefined, it replaces the existing field constraint.
Note: The range constraints do not have to match the data type of the stored field. That is, you could have a date-time constraint for a STRING field or an integer constraint for a FLOAT field, and so on.
You can set the following constraint attributes:
- date-time value
- pattern for a field value
- length
- integer value
See Content constraints for details.
Changes to journal record layouts
Four bytes have been added to the journal record header for user statistic entries: 1 byte to hold the IODEV number and 3 bytes for future use.
All user since-last statistics (LAST=) lines will now show the IODEV= value:
ST $$$ USERID='userid' ACCOUNT='accountname' IODEV='devicetype' LAST='acty'
For more information on journal records and user statistics, see the Rocket Model 204 System Manager's Guide.
Compatibility issues
This section describes any compatibility issues between V7.5 and prior versions of Model 204. An incompatibility arises if an operation that was previously performed without any indication of error, now operates (given the same inputs and conditions) in a different manner.
A normal bug fix resolving behavior that, although not indicating an error, was "clearly and obviously" incorrect, also introduces an incompatibility, but it might not be included below.
Change to the Ordered Index layout
Formerly all ORDERED NUMERIC fields came after all ORDERED CHARACTER fields in the Ordered Index. Now, the fields are interspersed in field code order.
ZFIELD Image
The ZFIELD image has been updated for this release. The image is used with $LSTFLD and $FDEF function calls. One change is that FDEF is now longer (to accommodate FDEF1, LOOPVAR, and FDEF2).
INTERCOMM is no longer supported
The INTERCOMM interface supports the use of Teletype and 3270 terminals in line-at-a-time mode, using the Model 204 IODEV=29 thread type.
INTERCOMM is no longer supported as of Model 204 version 7.5.
See the Rocket Model 204 Terminal User's Guide for a discussion of terminal interfaces.
User PDL overflow
The new SEQPDL parameter might require you to increase the size of the user Push Down List (using UTABLE LPDLST) by up to 3072 bytes, or more if you specify a value for SEQPDL that is larger than the 4096 default value.
LPDLST parameter maximum value
The maximum value for the LPDLST parameter has been increased from 32760 to 65536.
SSLIBSIZE parameter maximum value
The maximum value for the JANUS DEFINE command SSLIBSIZE parameter has been decreased from 32767 to 16384.
New and changed commands
DECREASE (new option: DYNAMIC)
The DYNAMIC option on the DECREASE command lets you decrease Table B dynamically, even if the file is open by others or has requests compiled against it.
DEFINE DATASET (new parameter: GDGRECNT)
The GDGRECNT parameter for the DEFINE DATASET command causes Model 204 to check the catalog information for the latest relative GDG generation number whenever allocating a GDG data set.
DEFINE FIELD (new or changed attributes)
In Model 204 version 7.5, the DEFINE FIELD command has new attributes information:
- the new CHUNK attribute, which improves the efficiency of range finds using ordered index processing
- many other FILEORG=x'100' related new or changed field attributes
DEFINE FIELDGROUP (new in V7.5)
The DEFINE FIELDGROUP command establishes the contents of a field group, including the fields and field groups associated with the field group being defined.
DELETE FIELD (changed to handle CAT and CTO fields)
The DELETE FIELD command has been changed to take CONCATENATION-OF (CAT) and COUNT-OCCURRENCES-OF (CTO) fields into account. DELETE FIELD does not allow deletion of fields referred to by an existing CAT or CTO field.
DELETE FIELDGROUP (new in V7.5)
The DELETE FIELDGROUP command deletes a field group from a Model 204 file.
DISPLAY FIELD (new option: COMMA)
In Model 204 version 7.5, the DISPLAY FIELD command has added the COMMA option, which uses commas to separate displayed field attributes.
DISPLAY MODMAP (new in V7.5)
DISPLAY MODMAP displays the Model 204 link map in address order. System manager privileges are required.
REGENERATE and REGENERATE ONEPASS (improved TO UPDATE option)
The TO UPDATE option of the REGENERATE and REGENERATE ONEPASS commands can now handle multiple files.
If TO UPDATE nn OF id is specified, it must appear only on the first FILE statement, and no other ‘TO’ options are allowed on subsequent files.
All additional files will be recovered as though they each specified the same 'TO UPDATE' option. Once the 'end of transaction' is reached, further processing will stop and all inflight transactions will be backed out.
RENAME FIELDGROUP (new in V7.5)
The RENAME FIELDGROUP command changes the name of a field group.
UNICODE (new codepage: 1154)
The UNICODE command now accepts 1154 as a codepage name. This codepage has 92 Unicode characters in the range U+0400 through U+045F, representing the Basic Russian alphabet and all of the Cyrillic extensions excepting the four which have grave accents.
Reliability enhancements
SEQPDL parameter
The new SEQPDL parameter controls the amount of free space that must be present in the user's Push Down List (PDL) in order for the SOUL sequencer to proceed with the next quad code. The minimum and default value is 4096 bytes. The maximum value is 8192 bytes. SEQPDL is a user resettable parameter and can be set on the user's parameter line or reset with the UTABLE command.
Formerly 1024 bytes of PDL free space were hardcoded internally in the Model 204 core. With 1024 bytes there were edge cases where abends would break files, resulting in ERROR 2126 USER'S PUSHDOWN LIST OVERFLOWED. SEQPDL is provided to allow enough PDL space so that all of the lower level journaling routines can process error conditions without breaking files.
If your applications are using close to the amount of PDL space currently set by the LPDLST value, you might need to increase LPDLST to reflect SEQPDL's increase in free space.
New and changed parameters
In addition to the following specific parameter changes, Model 204 parameter descriptions, for example as displayed by the VIEW command, are now in mixed case (unless translated to uppercase due to UPCASMSG.)
Note: The Sirius Mods parameters are merged with the Model 204 base as of Model 204 version 7.5, and they are available to all version 7.5 customers. The combined set of parameters is displayed on the List of Model 204 parameters page. The former Sirius parameters in that listing are marked with an (S).
DSPOPT (change to default setting)
The default setting for DSPOPT has been changed from X'00' to X'01'. The X'01' setting allocates space for servers in memory in chunks of 4K pages, not as a permanent contiguous area. This allocation lets you move fewer 4K pages, keeping the virtual storage allocated for servers in memory less fragmented and possibly using fewer paging tables.
ECPSIZE (change to max value)
The maximum value setting for ECPSIZE has been increased from 1310680 to 1966020 to accommodate more External Call Facility parameters.
FILEORG (new settings)
-
The FILEORG X'100' setting for enhanced data handling files is now available.
X'100' enables a number of enhancements to the file structure, including:
- Support for physical field groups
- The definition of as many as 32000 fields in a file
- System maintained Automatic fields
- Field constraints providing content validation
- Improved space management of fields containing Large Objects
- New DEFINE FIELD attributes, such as CHUNK
If X'100' is selected, the X'80' bit (optimized field extraction files) is automatically set.
- The FILEORG X'200' setting for large file support is now available.
X'200' allows files to hold up to 48 million records.
FISTAT (change to X'08' setting)
The FISTAT X'08' (file full) setting is now automatically cleared in a transaction back out file if table D is increased enough so that DSIZE is greater than or equal to DPGSRES+DPGSUSED.
MISCOPT (obsolete)
The MISCOPT parameter is now obsolete. In Model 204 version 7.5, MISCOPT is still viewable but is not resettable.
MODTIM (new in V7.5)
The MODTIM system parameter displays the most recent assembly date and time of the Model 204 load module.
OUTPUT (change to allow OUTPUT=DUMMY)
IODEV=3 threads definitions now allow OUTPUT=DUMMY. When defining IODEV=3 threads, if output is not required, the OUTPUT parameter can be coded as OUTPUT=DUMMY.
For example:
IODEV=3,INPUT=IOD3IN1,OUTPUT=DUMMY
This means that no DD statement is required for the output data set, and in cases where many IODEV=3 threads are defined to simulate a large number of users, this enhancement will reduce the number of DD statements required by one half.
RECLOCKO (X'04' bit now ignored)
The RECLOCKO X'04' bit is now ignored, and the extra information of the conflicting user number and lock time are now always available.
LRETBL (setting increase may be necessary)
Because there might be a slight increase in record locking table usage in V7.5, an increase in the value of the LRETBL parameter is advised. The amount of the increase is best estimated by multiplying by 16 the HWM HEADERS
value (from a MONITOR ENQ report), then dividing by the value of the NUSERS parameter. For example, if HWM HEADERS = 100000
and NUSERS=2000
, the recommended LRETBL increase is 16*100000/2000
, or 800.
RESPAGE (new in V7.5)
The RESPAGE parameter activates the APSY Precompiled Procedures in storage feature using above the bar pages by specifying a number of 4K operating system pages.
RETRVKEY (change to allow forward retrieve PF key)
New in this release, if you specify a non-zero setting of RETRVKEY:
- If you have set the
X'01'
orX'10'
bits of the RETRVOPT parameter, you can use a forward retrieve PF key, in addition to the backward retrieve PF key specified by RETRVKEY.Note: If either of these bits is set, the
X'02'
bit is strongly recommended as well. - The size of the allocated storage area, and hence the number and length of input lines available for retrieval, is specified by the value of the RETRVBUF parameter.
SEQPDL (new in V7.5)
The SEQPDL parameter controls the amount of free space that must be present in the user's Push Down List in order for the SOUL sequencer to proceed with the next quad code. SEQPDL allows enough PDL space for the lower level journaling routines to handle error conditions properly without breaking files and causing ERROR 2126 USER'S PUSHDOWN LIST OVERFLOWED.
SESMAXTO (new in V7.5)
The SESMAXTO parameter can be used limit the maximum session timeout value or to cause all current closed sessions to be immediately discarded.
SMFSVC (obsolete)
The SMFSVC parameter is obsolete as of Model 204 version 7.5.
UPCASMSG (new in V7.5)
The UPCASMSG parameter can be used to translate messages issued by Model 204 to uppercase; otherwise (depending on the message being issued) they are displayed in mixed (upper and lower) case.

Explanation: TBD
0761:
ATRPG*ASTRPPG EXCEEDS maxentries
Explanation: You attempted to initialize a file that was created with invalid parameters. The number of dictionary entries is determined by the product of the parameters ATRPG and ASTRPPG. The maximum allowed product is 4000 (attribute dictionary entries), or 32000 for a FILEORG=x'100' file. The INITIALIZE command is rejected.
Response: The file must be recreated. Retry the CREATE command specifying ATRPG and ASTRPPG parameter values such that the product of the two is less than maxentries.
C 0 4 AUDITER
0790:
FILE TOO BIG
Explanation: The total number of records possible in Table B exceeds 342 segments for files that do not have the FILEORG X'200' bit set and 1024 segments for files that have the FILEORG X'200' bit set.
The number of potential record numbers per segment is 49,152.
The number of possible segments in Table B is calculated by the following formula:
((BSIZE * BRECPPG) / 49,152)) + (1 if remainder not 0)
If the result exceeds 342 or 1024 respectively too many segments result and MODEL 204 rejects the CREATE command.
File manager response: Make the file smaller (by specifying a smaller BSIZE or smaller BRECPPG), or divide the file into smaller pieces and use the file group feature to process them as a single logical file.
Return Codes: C 0 4 AUDITER
0797:
BSIZE*BRECPPG EXCEEDS MAXIMUM VALUE
Explanation: The product of BSIZE and BRECPPG must not exceed 16,777,216 for regular Model 204 files (which do not have the FILEORG X'200' bit set) and 50,331,648 for files that have the FILEORG X'200' bit set. These numbers specify the maximum number of records allowed in a single Model 204 file.
The CREATE or INCREASE command is rejected.
File manager response: Retry the command, specifying values for BSIZE and BRECPPG so that BSIZE*BRECPPG does not exceed the limit. See Managing file and table sizes for more information.
Return Codes: C 0 4 AUDITER
1050: CCATEMP FULL: operation or pooltype
Explanation: The operation being performed required an extra page from CCATEMP, but there were no free pages available. CCATEMP is defined by the system manager and provides a set of work pages that are assigned on request to various users. If a request gets this message, it might be because some other user is holding a large number of CCATEMP pages.
The message specifies either the operation being performed, or the section ("pool") of CCATEMP that was full.
operation can be one of:
- $BLDPROC
- "USE PROCEDURE" COMMAND
- WHILE INITIALIZING SORT
- FOR FRV KEYS
- WHILE GENERATING RECORDS TO BE SORTED
- WHILE GENERATING ORDERED INDEX SORTED RECORDS
- WHILE PERFORMING SORT
pooltype can be one of:
- SMALL MODEL PAGE POOL
- SMALL MODEL PAGE POOL AND EXPANSION PAGE POOL
The current request is cancelled.
If the operation was $BLDPROC or USE PROCEDURE COMMAND, then the temporary procedure that was being written is deleted, except for its very last CCATEMP page, which is retained for information purposes.
In some cases the user is restarted and, if the user was in the process of updating any files, MODEL 204 marks them physically inconsistent.
CCATEMP pages below 64K are allocated from the small model pool. CCATEMP pages above 64K are allocated from the expansion area pool.
The pooltype specified in the message indicates whether you exceeded the capacity of the small model pool or both the small model and expansion area pools.
Response: Notify your system manager.
System Manager response: Recover the physically inconsistent files using one of the following procedures:
- Roll back/roll forward
- File reorganization procedure described in File reorganization and table compaction
- The RESTORE command for restoring previously dumped copies
This message is informational, but it indicates a need to increase the space allocation for CCATEMP. As the size of CCATEMP is fixed at initialization, it is necessary to bring down MODEL 204 to increase it.

LOUTPB %C TO %C
Explanation:
LOUTPB has been increased or decreased, to the value given in the message.
With a full-screen terminal the value is 1.5 times the minimum for that model number, rounded
up to a multiple of 8.
A model 2 terminal results in a LOUTPB of 3200.
A model 5 terminal results in a LOUTPB of 5664.
If NBKPG is greater than 0, the largest allowable value for LOUTPB is PAGESZ minus 40, so the value can be decreased for this reason.
User Response: No response is needed. This message is for information only.

Explanation: The procedure action cannot be taken for one of the following reasons:
- The procedure is in use by another user.
- The procedure is not in the file.
- The user does not have the correct privileges to change the procedure.
- If a RENAME or ASSIGN has been attempted, the alias might already exist.
Response: Make sure that the procedure name is spelled correctly.
If the named procedure is in use, retry the command when the procedure is no longer in use. Otherwise, arrange to place the

Explanation: You have attempted to reset a parameter either below the minimum or above the maximum allowed for it. Model 204 has reset the parameter to the correct minimum or maximum.
Response: Retry the command with a value within the correct range, or leave the value as is, since Model 204 has already reset the parameter to the correct minimum or maximum.
For PARAMETER=ESIZE, if you specify:
- A zero value, which is the equivalent of Not Applicable, no pages are allocated for Table E.
- A non-zero value, then the minimum of 20 pages allocated for Table E is enforced.

2126:
USER'S PUSHDOWN LIST OVERFLOWED
Explanation: The user's pushdown list is an internal stack for maintaining state information for user threads across internal Model 204 subroutines. The user pushdown list lives in each user's server. Its size requirement depends on the complexity of the command or User Language request.
This message is issued whenever Model 204 detects that pushdown list data has spilled into adjacent control structures. Because of potential corruption the user is restarted.
Response: Increase the size of the user pushdown list by using the LPDLST parameter of the UTABLE command. Notify your system manager.
System Manager Response: If this becomes a frequent occurrence, consider more permanent changes to LPDLST and SERVSIZE, since the pushdown list is a server component.
Return Codes: C 0 4 CANCEL

2940:
Use of filename after INITIALIZE keyword discouraged because it gave different results prior to version 7.5
Explanation: This message indicates that the format of the INITIALIZE command as entered does not conform to the syntax of:
INITIALIZE [KEEPDEF[S]]
Prior to version 7.5, it was possible to place any text on the INITIALIZE command, and if it was anything other than KEEPDEF[S], it was ignored. In version 7.5, the syntax of INITIALIZE command is checked for strict correctness.
If you have entered the name of the file being initialized AFTER the INITIALIZE command keyword, you can either correct the command (that is, remove the filename after the INITIALIZE command keyword) or use the MSGCTL M204.2940 command as described below so that the command can continue to work.
File manager response: The most direct response is to correct the command to conform to the proper syntax, that is, remove extraneous strings after the INITIALIZE command keyword.
System manager response: If the file manager has chosen to keep the filename after the INITIALIZE command keyword, and the filename is the same as the name of the file being initialized, you can have the following command executed at any time before the INITIALIZE command is executed:
MSGCTL M204.2940 NOCOUNT
This action represents a very special case for the NOCOUNT option of MSGCTL.
Normally, the NOCOUNT option only changes a message such that it does not increment the count of counting errors, but does not directly affect the operation which issued the error message.
For this message, however, setting the NOCOUNT operation indicates that this condition is to be allowed, and normal processing of the INITIALIZE command will continue.
Issuing the above MSGCTL command with version 7.5 of Model 204 will not present any risk of an incorrect operation of INITIALZE. The only caution to be observed is that in prior versions of Model 204, a filename after the INITIALIZE command keyword is NOT checked against the name of the file being initialized, and so the use of the filename after the INITIALIZE command keyword might be a risky practice if it is possible such a command might be used in a prior version of Model 204.
Return codes: C 0 4 AUDITER
2941:
FILE BEING INITIALIZED DOES NOT MATCH NAME GIVEN AFTER INITIALIZE COMMAND: %C
Explanation:
This message indicates that the format of the INITIALIZE command as entered does not conform to the syntax of:
INITIALIZE [KEEPDEF[S]]
Prior to version 7.5, it was possible to place any text on the INITIALIZE command, and if it was anything other than KEEPDEF[S], it was ignored. In version 7.5, the syntax of INITIALIZE command is checked for strict correctness.
In some cases, users have entered the name of the file being initialized AFTER the INITIALIZE command keyword, but this message indicates that whatever string you entered after the INITIALIZE command keyword is not the name of the file being initialized.
File manager response:
Correct the command. The most direct response is to correct the command to conform to the proper syntax: that is, remove extraneous strings after the INITIALIZE command keyword.
However, if the system manager has performed a MSGCTL M204.2940 NOCOUNT command, and you want to enter the correct filename on the INITIALIZE command, that will allow the INITIALIZE operation to proceed.
System manager response:
If the file manager is unable to correct the INITIALZE command, you can have the following commands executed at any time before the INITIALIZE command is executed:
MSGCTL M204.2940 NOCOUNT MSGCTL M204.2941 NOCOUNT
These actions represent a very special case for the NOCOUNT option of MSGCTL.
Normally, the NOCOUNT option only changes a message such that it does not increment the count of counting errors, but it does not directly affect the operation which issued the error message.
For this message, however, setting the NOCOUNT operation indicates that this condition is to be allowed, and normal processing of the INITIALIZE command will continue.
Issuing MSGCTL M204.2941 NOCOUNT is not recommended, because this results in what might appear to be checking of the filename when in fact it is not checked.
Issuing MSGCTL M204.2940 NOCOUNT does not present any risk with version 7.5 of Model 204, but, as discussed in the System Manager response section of message 2940, this practice should be done with caution.
Return codes: C 0 4 AUDITER
2942:
Extraneous string after field attribute list: %C
Explanation: This message indicates that the format of the INITIALIZE command as entered for a hashed, sorted, or record security file does not conform to the syntax of:
INITIALIZE [SORT fldName (attributes)] [HASH fldName (attributes)] [RECSCTY fldName (attributes)]
In particular, it indicates that some string followed the right parenthesis (')') of the attribute list.
Prior to version 7.5, nothing after the closing parenthesis was checked.
File manager response: Correct the command. There should be no string after the right parenthesis.
System manager response: If the file manager is unable to correct the INITIALZE command, you can have the following command executed at any time before the INITIALIZE command is executed:
MSGCTL M204.2942 NOCOUNT
This action represents a very special case for the NOCOUNT option of MSGCTL. Normally, the NOCOUNT option only changes a message such that it does not increment the count of counting errors, but does not directly affect the operation which issued the error message.
For this message, however, setting the NOCOUNT operation indicates that this condition is to be allowed, and normal processing of the INITIALIZE command will continue.
Issuing MSGCTL M204.2942 NOCOUNT is not recommended, because if you issue this command the string after the right parenthesis will not be analyzed.
Return codes: C 0 4 AUDITER
2943:
Error using filename phrase for file %C: restriction
Explanation: This message indicates that the format of the INITIALIZE command as entered does not conform to the syntax of:
INITIALIZE [KEEPDEF[S]]
Prior to version 7.5, it was possible to place any text on the INITIALIZE command, and if it was anything other than KEEPDEF[S], it was ignored. In version 7.5, the syntax of INITIALIZE command is checked for strict correctness.
In some cases, users have entered the name of the file being initialized AFTER the INITIALIZE command keyword, but this message indicates that the syntax requires some modification for the particular file being initialized.
File manager response: The command should be corrected; the most direct response is to correct the command to conform to the proper syntax, that is remove extraneous strings after the INITIALIZE command keyword.
However, if the system manager has performed a MSGCTL M204.2940 NOCOUNT command, you can modify the command as indicated by the restriction shown in the M204.2943 text.
System manager response: If the file manager is unable to correct the INITIALZE command, you can have the following commands executed at any time before the INITIALIZE command is executed:
MSGCTL M204.2940 NOCOUNT MSGCTL M204.2943 NOCOUNT
This action represents a very special case for the NOCOUNT option of MSGCTL. Normally, the NOCOUNT option only changes a message such that it does not increment the count of counting errors, but does not directly affect the operation which issued the error message.
For this message, however, setting the NOCOUNT operation indicates that this condition is to be allowed, and normal processing of the INITIALIZE command will continue.
Issuing MSGCTL M204.2943 NOCOUNT is not recommended, because this bypasses the checking that is intended by the restriction shown in the M204.2943 text.
Issuing MSGCTL M204.2940 NOCOUNT does not present any risk with version 7.5 of Model 204, but, as discussed in the system manager response for M204.2940, this practice should be done with caution.
Return codes: C 0 4 AUDITER
2944:
Should have end of cmd command but instead found: string
Explanation: This message indicates that the format of the command indicated by cmd as entered does not conform to command syntax.
User response: Correct the command, either by simply removing string and any following strings or else by correcting the command to conform to the proper syntax.
File manager response: If the cmd in the M204.2944 text is INITIALIZE, this message indicates that the format of the INITIALIZE command as entered does not conform to the syntax of:
INITIALIZE [KEEPDEF[S]]
Prior to version 7.5, it was possible to place any text on the INITIALIZE command, and if the text was anything other than KEEPDEF[S], it was ignored. In version 7.5, the syntax of INITIALIZE command is checked for strict correctness.
The command should be corrected as described in the user response above.
System manager response: If the file manager is unable to correct the INITIALZE command, you can have the following command executed at any time before the INITIALIZE command is executed:
MSGCTL M204.2944 NOCOUNT
This action represents a very special case for the NOCOUNT option of MSGCTL. Normally, the NOCOUNT option only changes a message such that it does not increment the count of counting errors, but does not directly affect the operation which issued the error message.
For this message, however, setting the NOCOUNT operation indicates that this condition is to be allowed, and normal processing of the INITIALIZE command will continue.
Issuing MSGCTL M204.2944 NOCOUNT is not recommended, because whatever string was indicated on the INITIALIZE command is not checked.
Return codes: C 0 4 AUDITER
