Syntax

ISSYSOUT('ddname','procstep','pgmstep','jobname')

In this syntax

• ddname is the name of the DD statement that references the sysout. Must be in quotes. Mandatory.
• procstep is the name of the procedure step that produced the sysout. Must be in quotes. Optional.
• pgmstep is the name of the program step that produced the sysout. Must be in quotes. Optional.
• jobname is the name of the job that produced the sysout. Must be in quotes. Optional. If JOBNAME is not specified, the default value is the current job.

The ISSYSOUT function returns the value TRUE if the sysout exists and the value FALSE if the sysout does not exist. This enables you to avoid an attempt to access a nonexistent sysout and thereby avoid an abend with the return code 4091 when the sysout is not found on spool.

The four arguments are identified by position. A blank argument is represented by one or more blanks enclosed by quote marks.
