PARM

Purpose  

The PARM parameter identifies the file that contains frequently used runtime parameters.

Syntax  

where

 

Syntax Element

Definition

ddname

ddname (z/OS platform) of the file containing the frequently used runtime parameters

Usage Notes  

The PARM runtime parameter saves frequently used runtime parameters in a separate parameter file. Its functionality is analogous to DEFAULT.

ARCMAIN reads the PARM file, then builds the parameter list line and appends the actual parameter list to it. PARM or PARM=ddname must be the first parameter in the parameter list, meaning that PARM cannot appear in the middle of the parameter list.

On IBM platforms, if PARM is specified without a ddname, then the default ddname is SYSPARM.

Use the following NO parameters to disable any previously specified runtime parameters, including those specified in PARM:

  • NOHALT
  • NOPAUSE
  • NORESTART
  • NOHEX
  • NOVERBOSE
  • NOERRLOG
  • The SESSIONS and CHECKPOINT parameters can be specified more than once to override previous instances of these parameters. However, the last instance of the parameter is the value that is used. For example, if these runtime parameters are specified once in PARM, then one or more times in the parameter list, only the last instance of the parameter is used.

    Example  

    The next example illustrates the use of PARM, including an instance when more than one parameter (in this case, SESSIONS) is specified in PARM:

       //REST EXEC PGM=ARCMAIN,PARM='SESSIONS=80 SESSIONS=40 VERBOSE'

    In the example, 40 sessions are used, not 80, because SESSIONS=40 is the last instance of the parameter specified in PARM.
