Modification of the default values in the System Environment

You can modify the default values in the System Environment.

However, do so only when you need to modify the default values in the System Environment for operational reasons.

It is normally recommended that you only make modifications to the System Environment Settings file (HULFT.PARMLIB(HULPRM)), without changing the default values.

Note

  • If you perform the procedure explained here, modifications will be made to the environment in which you are currently using HULFT. Before performing this procedure, be sure to refer to Backup in HULFT Ver.10 and create a backup for HULFT load module library.

  • Since members of the library are updated, the capacity of the existing HULFT load module library may be insufficient.

  • If you modify the default values for tag names that do not have default values, shown in the list of System Environment Settings in Administration Manual, you will be unable to return them to their default values. In this case, restore HULFT load module library from the backup.

  • After you use this program, rerun the following HULFT resident programs:

    • Send program (XRSND)

    • Receive program (XRRCV)

    • Observe program (XRACCPT)

System Environment Settings Default Value Modification Program (XRPRMSET)

Program Name

XRPRMSET

Execution parameters (for EXEC statement)

PARM='SOURCE=XXXXXXXX, OBJIN=XXXXXXXX, OBJOUT=XXXXXXXX'

SOURCE

Source DD Name

You can specify a source DD name for the assembler program. If this parameter is not specified, the default value 'SYSIN' is used.

OBJIN

Object program input DD name

You can specify an input DD name for the object program of the assembler program. If this parameter is not specified, the default value 'SYSLIN' is used.

OBJOUT

Object program output DD name

You can specify an output DD name for the object program of the assembler program. If this parameter is not specified, the default value 'SYSLIN' is used.

    Specify a name in compliance with the data set naming conventions of the operating system, using alphanumeric characters up to 54 bytes in length. You can specify Sequential Organization files and partitioned data sets (PDS).

    If you omitted the JCL XRSYSIN definition card, HULFT refers to the settings in the System Environment Settings file (HULFT.PARMLIB(HULPRM)) specified for the 'HULPRMFILE=' tag to perform this operation.

    If you modify the settings in the System Environment Settings file (HULFT.PARMLIB(HULPRM)) specified for the 'HULPRMFILE=' tag, all JCL jobs for which the XRSYSIN definition card was omitted are affected.
= Remarks =

  • For details about the meanings and settings for each field in the System Environment Settings, refer to the following:

    HULFT10 for zOS Administration Manual : System Environment Settings

  • When the first byte of a tag name is '*,' the line will be handled as a comment.

  • You can omit the definition card. The default values of omitted tag names are not modified.
