IN=input_transaction_code parameter for procedures

You can set the IN= parameter using the DFSOPT DD statement in IMS-supplied procedures. The syntax for the IN= parameter is:

IN=char str (No default)

For more information, see DFSOPT DD in DD statements for IMS procedures.

This parameter is necessary only when the application program intends to access the message queues. You cannot schedule a BMP with an IN= parameter specified against a PDIR with an associated SMB that is already scheduled and is SCHDTYP=SERIAL. Doing so results in ABENDU0457 when the BMP is scheduled.

If the IN= parameter is omitted, the BMP is treated as a batch-oriented BMP.
