APARM= parameter for procedures

Use the APARM= parameter in procedures to specify the 1- to 32-character parameter passed to the application program as part of the information returned in the INQY call with the ENVIRON or ENVIRON2 subfunctions.

Note: The PARM=() specified on the EXEC PGM=DFSRRC00 statement is limited to 100 characters. Thus, if you start a dependent region with other positional parameters that follow APARM=, the number of APARM characters you can specify might be fewer than 32.

The parameter must be enclosed in single quotation marks (') if special characters are used. Embedded commas (,) are not allowed.
