HLI: Model 204 completion and ABEND codes

Overview

This topic describes the completion codes that may be encountered when using the Model 204 HLI facility. There are two broad categories of completion codes:

• Return codes for HLI calls
• Job run ABEND codes

This topic presents the codes in the following tables:

• Completion return codes 0-3 lists completion codes that are returned by Model 204 to the host language application program for operations which completed normally, or with a warning. RETCODE is 0, 1, 2, and 3.
• Completion return codes 4 and greater lists completion codes that usually indicate that a call was unsuccessful. RETCODE is greater than or equal to 4.
• Job run ABEND codes lists completion codes that are generated for severe errors that cause the HLI job run to abend.

For more information about individual completion return codes for conditions that are unique to a specific function call, refer to the usage notes for the particular call.

Completion return codes 0-3

The following table describes the completion codes that are returned by Model 204 to the host language application program for operations which completed normally, or with a warning. RETCODE is 0, 1, 2, and 3.

Completion return codes 0-3

Code	Call(s)	Description
0	IFATTN	IFDIAL connection completed.
	IFCHKPT	Checkpointing status depends on which function code is specified in the call: Function code is 0: Checkpoint not currently in progress, parameter 3 unaltered. Function code is 1: Checkpoint successfully initiated. Function code is 3: Checkpoint successfully completed.
	IFDIAL IFDIALN	IFDIAL connection established.
	IFHNGUP	IFDIAL connection dropped.
	All except IFCHKPT	Function completed successfully.
1	IFCHKPT	Checkpointing status depends on which function code is specified in the call: Function code is 0: Checkpoint in progress, parameter 3 set to its ID. Function code is 2: Checkpoint completed successfully, parameter 3 set to its ID.
	IFGET IFFTCH	Nonnumeric value could not be converted, or integer portion of the value is too large for output area. Errors may occur for B, P, F, and Z edit formats.
	IFMORE	Nonnumeric value could not be converted, or integer portion of the value is too large for output area. Errors may occur for B, P, F, and Z edit formats.
	IFREAD	Call IFWRITE next to provide Model 204 with input.
	IFSTRT (IFAM1)	Illegal call. Thread already exists.
	IFWRITE	Call IFWRITE next to provide Model 204 with input.
2	IFCHKPT	Checkpoint request timed out. Checkpoint not taken.
	IFFLS	The file indicator was used to identify the file of the current record and no current record was found.
	IFFTCH	Indicates no more records to fetch in the current set.
	IFREAD	Call IFREAD next to get more output from Model 204.
	IFRPRM and IFSPRM	TBO has been enabled or disabled for a file such that the group of files in the job violates the restriction that TBO files may not open for update while any non-TBO file is open on a read-only thread. The parameter reset was successful, but the M204.0498 error was issued and the file is closed.
	IFWRITE	Call IFREAD next to get more output from Model 204.
	Any other call	Indicates no records in the current set.
3	IFCHKPT	Caller is not allowed to wait for checkpoints. Call ignored.
	All except IFCHKPT	Return code number reserved for future use, or control of necessary resource could not be obtained and call may be reexecuted.

Completion return codes 4 and greater

The following table describes the completion codes which usually, but not always, indicate that a call was unsuccessful. RETCODE is greater than or equal to 4.

Note: The error message is written to the Model 204 journal and is available to the application program using the IFGERR call.

Completion return codes 4 and greater

Code	Call(s)	Description
4	All calls	Error message has been produced. For more information about conditions that are unique to a specific function call, refer to the Notes for the particular call.
5	IFCHKPT	Checkpoint not active during recovery. Call ignored.
	Compiled IFAM calls	The name used by an E (execute) call has not been defined.
6	Compiled IFAM calls	The name used by an E (execute) call or standard compile and execute call has been defined by an incompatible function. IFGET, IFMORE, and IFPUT specs can be shared, but they cannot be referred to by IFFIND calls. Similarly, IFFIND compilations cannot be referred to by IFGET-type calls. IFFIND and IFFNDX cannot share specs.
7	Compiled IFAM calls	Not enough space exists to compile the current call. Error message indicates which server table is full. Use IFFLUSH to recover from this condition. Many Host Language Interface calls not directly affected by the Compiled IFAM feature use space in QTBL and VTBL. These functions return a code of 4 if either table fills.
10	IFBREC IFSTOR IFPUT IFUPDT	For an updating call where the FILEMODL file option is set to NUMERIC VALIDATION, Model 204 encountered invalid values for BINARY and FLOAT numeric field types. For more information about FILEMODL, see File model feature. For information about binary and float values, see Storing data in fields.
	All calls	The function has been cancelled. The transaction is automatically backed out and control is returned to the application program.
12	IFREAD and IFWRITE	IFREAD called when IFWRITE was expected, or IFWRITE called when IFREAD was expected.
	IFREAD	No output ready from Model 204; call IFWRITE to provide more input. The answer area is not altered.
15	IFEFCC and IFERLC	An updating function received an error when there was no conflict to search for.
40	IFBOUT	An IFBOUT was issued from a read-only thread. IFBOUT is only valid on update threads.
	All calls	Function requires update privileges, but none were granted. Issue IFSTRT with thread update privileges and give file or group password with update privileges.
50	All calls (IFAM2 and IFAM4)	An updating function was issued on a thread which has been quiesced for checkpointing by a previous call to IFCHKPT.
60	All calls	No current file or group. Function cannot complete.
61	All calls	Function attempted against file or group with broken FISTAT setting. Function cannot complete.
80	All calls in IFAM1	No current thread. For IFSTRT support, call IFSTRT. For IFDIAL support, call IFSETUP.
90	IFDIAL IFDIALN	An IFDIAL connection already exists for this application program. The attempt to establish more than one simultaneous connection for this application is ignored.
	IFSTRT in IFAM1	Illegal call to IFSTRT. A thread already exists.
	IFSTRT in IFAM2 and IFAM4	Model 204 is not yet available for user processing. Recovery may still be in progress. Call IFSTRT again.
95	IFDTHRD and IFSTHRD	Nonexistent new thread specified. Call ignored.
96	IFDTHRD	New thread is already current thread and thus is not detached.
100	in IFAM1	LOGIN failed.
	in IFAM2 and IFAM4	No current thread exists. Call IFSTRT.
	IFATTN	The connection was lost.
	IFHNGUP	The connection was lost prior to call.
	IFREAD	No current Model 204 connection exists or the connection is lost.
	IFSTRT in IFAM2 and IFAM4	LOGIN failed.
	IFWRITE	No current Model 204 connection exists or the connection is lost.
101	IFDIAL in IFAM1	Invalid BATCH204 module loaded. Check STEPLIB for correct release.
	IFSTRT in IFAM1	Failure to dynamically load the IFAM1 load module, because the entry point was specified incorrectly when relinking.
200	IFBREC IFPUT IFSTOR IFUPDT	A uniqueness violation has occurred (field level constraint). A UNIQUE violation corresponds to errors handled by ON FCC ON units in SOUL. For information about ON units, see On units 2.
202	IFPUT IFSTOR IFUPDT	An AT-MOST-ONE violation occurred (field level constraint). An AT-MOST-ONE violation corresponds to errors handled by ON FCC ON units in SOUL. For information about ON units, see On units 2.
260	IFOPEN	A file or group could not be opened.
300	All calls	Thread restarted in Host Language Interface Model 204 service program. Call lost.
325	in IFAM2	IQB not large enough. Adjust the Model 204 parameters LIBUFF, LOBUFF, and IFAMBS as necessary.
350	in IFAM2	Invalid string length. Adjust the Model 204 parameters LIBUFF and LOBUFF as necessary.
400	IFSTRT and IFSETUP in IFAM2 and IFAM4	Invalid language code.
	Other calls in IFAM2 and IFAM4	Invalid parameter list.
500	IFCALL	Invalid function number passed to IFCALL.
	in IFAM1 using IFDIAL	Invalid function called.

	All other calls	Model 204 is no longer available.
1001	in IFAM2 and IFAM4	Host Languages Interface Model 204 service program is not up, the Host Language interface is halted or drained, or no host language threads were defined in Model 204 This may indicate that the IFAM4 load module was link-edited without the REUS option.
	IFDIAL	Host Language Interface Model 204 is not up, or no IODEV=39 statements were included in initialization, or CRAM channel name does not exist. Connection is impossible.
1002	in IFAM2	Insufficient SQA or CSA space to use CRAM connection.
1003	in IFAM2 and IFAM4	Insufficient memory in the IFAM application to allocate the necessary control blocks.
	IFDIAL IFDIALN	Not enough memory for CRAM open.
1004	in IFAM2	An initial IFCSA call was not made.
1nnn	IFFNSH in IFAM1	IFFNSH returns 1000 and the highest Model 204 journal error message return code encountered during the run.

Job run ABEND codes

The follwing table describes the user ABEND completion codes that are generated when Model 204 detects severe errors and abends the HLI application program job run.

Job run ABEND codes

Code	Job type	Description
100	IFAM1	CCASNAP DD statement is missing.
250	IFAM2 and IFAM4	Invalid parameter list. Completion code could not be set.
1000	IFAM2	Serious CRAM error. Save all output from application and Host Language Interface Model 204 service program for Technical Support personnel.
