Record maintenance

FILEMGMT provides you with an interface for performing all your record maintenance operations. This section describes how to perform the following operations:

  • List records in new and existing files.
  • Select the records you want to define, redefine, delete, and rename.
  • Define and redefine records.
  • Stage records in preparation for executing DEFINE, REDEFINE, DELETE, and RENAME commands.

Record Name List screen

To display the Record Name List screen, you can optionally:

  • Press the F4 (RECords) key from the Field Attributes screen. FILEMGMT displays the Record Name List screen in DEFINE mode.
  • Select a Record maintenance function from the primary screen. FILEMGMT displays the Record Name List screen in the mode corresponding to the selected function.

You use the Record Name List screen to:

  • Specify the names and frequency of the records in a file you are creating. A record name represents a record type.
  • View records in an existing file, define additional records, and select records you want to redefine, delete, or rename.

If you are defining new records for a new or existing file, FILEMGMT displays the Record Name List screen in DEFINE mode:

Record Name List screen in DEFINE mode

FILEMGMT Record Name List Line 1 of 11 Enter and select with an 'X' the records you want to DEFINE to the file Filename: PERSONNL | | No. of | Expected | Occurrence | | Recordname | Records | Increase (%) | in File | Cmd -------------------------------------------------------------------- X PERSONNL | ________ | ___ | 100.0% | *** _ ____________________ | ________ | ___ | | _ ____________________ | ________ | ___ | | _ ____________________ | ________ | ___ | | _ ____________________ | ________ | ___ | | _ ____________________ | ________ | ___ | | _ ____________________ | ________ | ___ | | _ ____________________ | ________ | ___ | | _ ____________________ | ________ | ___ | | _ ____________________ | ________ | ___ | | _ ____________________ | ________ | ___ | | _ ____________________ | ________ | ___ | | ===> 1=HELp 2=DOCument 3=QUIt 4=FIElds 5=WIDen 6=COMmands 7= 8=FORward 9=SIZe 10= 11=RECdefn 12=END

The above record name list has an entry for a record name with the same name as the file. FILEMGMT creates this entry automatically.

You can perform these operations:

  • Rename the entry by typing over the displayed name.
  • Type additional record names, one record per line.
  • Specify for each record name the number of records and expected increase to the number of records. (No. of Records is required input.)
  • Proceed to the Record Definition screen to define the contents of the new entries.

If you are redefining, deleting, or renaming records, FILEMGMT displays the Record Name List screen in the mode corresponding to your requested function.

The following screen was invoked by selecting Redefine for Record on the primary screen:

Record Name List screen in REDEFINE mode

FILEMGMT Record Name List Line 1 of 2 Select the records you want to REDEFINE with an 'X' Filename: PERSONNL | | No. of | Expected | Occurrence | | Recordname | Records | Increase (%) | in File | Cmd -------------------------------------------------------------------- _ EMPLOYEE | 1000 | ___ | 29.4% | *** _ DEPENDENTS | 2000 | 20 | 70.6% | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ===> 1=HELp 2=DOCument 3=QUIt 4=FIElds 5=WIDen 6=COMmands 7= 8= 9=SIZe 10= 11=RECdefn 12=END

If you specified a particular record name on the primary screen, FILEMGMT displays an X in the prefix area of this record.

Staged records display the command for which they are staged in the Cmd column. Nonstaged records have a blank in the Cmd column, as in the above screen. Staging is discussed in Staging entries.

You can scroll forward and backward to view additional record names by pressing the F8 (FORward) and F7 (BACkward) keys. You can scroll forward 100 lines, which corresponds to FILEMGMT's record number limit.

Record Name List screen input

FILEMGMT displays or prompts you for the following information:

Prompt Response
Filename FILEMGMT displays the name of the file that you entered on the primary screen.
Recordname

If you are creating a new file, FILEMGMT displays a single record name that is the same as the file name.

If you are viewing an existing file and did not specify a particular record name on the primary screen, FILEMGMT lists all the records in the file.

Cmd

Displays the status of the record shown on the line:

  • If the record is currently staged (in the process of being changed), FILEMGMT displays the command that was generated for the record. The command is one of the following:
    ***Record name is new.
    DEFRecord is being defined.
    REDRecord is being read.
    DELRecord is being deleted.
    RENRecord is being renamed.
    R/RRecord is being redefined and renamed.

    Record operations might be staged if you begin to define, redefine, delete, or rename records and then end your FILEMGMT session without executing the commands that were generated. When you begin a new session, these records are shown as being staged.

  • If the record is not currently staged, this column is blank.
  • If a record name is added during a DEFINE operation and you press Enter, this column contains asterisks (***).

A record's Cmd status determines whether you can issue a particular command for the record. Command status, below, is a table that summarizes your options (where an X indicates the command is valid for the record).

No. of Records Type the number of records of the specified record name to be stored in the file. For a new file, the number represents the initial number of records. Valid values are:
  • 1-16777216 for non-RDFS files
  • 1-98304 for RDFS files
Expected Increase (%) Type the expected percentage of increase (0-100) in the number of records of the specified record name. The number represents the expected increase during the life of the file. If you do not enter a number in this column, FILEMGMT uses only No. of Records to calculate the size of the file.
Occurrence in File FILEMGMT computes this value from No. of Records and Expected Increase, and it displays the value.

Record operations

Follow these steps to stage records for a particular function.

Defining records

To DEFINE records:

  1. Enter the record names in the Recordname column.

    To enter new record names, type in the names (1-70 characters). Use the standard Model 204 naming conventions.

    To enter new records for an existing file, type the names at the bottom of the list. To enter a record name that is longer than the space provided (20 characters), position the cursor on the record name. Press the F5 (WIDen) key to advance to the Widen screen.

    You can remove new names before you end the session. Type a D in the prefix area to the left of the new name. The deletion removes a line from the display, but does not affect the physical data.

  2. Type X to the left of the record names to select them.
  3. Press F11 (RECdefn).

    The Record Definition screen displays the records you selected in the order in which they are listed on the Record Name List screen. The records are staged for DEFINE.

Redefining records

To REDEFINE records:

  1. On the main menu, using the record option, select option 2.
  2. Type X to the left of the record names to select them.
  3. Press F11 (RECdefn).

    The Record Definition screen displays the records you selected in the order in which they are listed on the Record Name List screen. The records are staged for REDEFINE.

Deleting records

To DELETE records:

  1. On the main menu, using the record option, select option 3.
  2. Type X to the left of the record names to select them.
  3. Press one of the following to stage the records for DELETE:

    F2 (DOCument) F4 (FIElds) F6 (COMmands) F9 (SIZe) F11 (RECdefn) F12 (END)

    Press F3 (QUIt) to cancel the deletion.

Renaming records

To RENAME records:

  1. On the main menu, using the record option, select option 4.
  2. Type X to the left of the record names to select them.
  3. Type over the existing names. Press the F5 (WIDen) key to enter a name that has more than 20 characters.
  4. Press one of the following to stage the records for RENAME:

    F2 (DOCument) F4 (FIElds) F6 (COMmands) F9 (SIZe) F11 (RECdefn) F12 (END)

    Press F3 (QUIt) to cancel the operation.

New Fieldname or New Recordname: If you entered a new record name for Field, Record or Field Group Name on the primary screen:
  1. Type the name of the new record to which FILEMGMT is to copy the source record. The record name cannot already exist.
  2. Press F12 (END). FILEMGMT copies the record.

If you did not enter a name for the source record on the primary screen, FILEMGMT displays the following message:

** All Records **

Do the following:

  1. Do not type a new record name.
  2. Press F12 (END). FILEMGMT copies all records from one file to another. The copied records have the same names as the original records, but are prefixed (qualified) by the Copy to FILE name.

Note: A record is not copied to the target file if the file already contains a record with an unqualified name (name without the file name prefix) that is the same as the record name in the source file. FILEMGMT displays a WARNING message when it copies all records and finds entries with duplicate unqualified names. The warning messge indicates the number of records that can be copied.
