Question:

Why it the assemble parameter NOASA changed to ASA during assemble ? The JCL in the processor has NOASA passed through the PARM keyword. The assemble listing is showing ASA.

Answer:

This depends on the RECFM of the SYSPRINT allocated dataset. If SYSPRINT is allocated to a file with RECFM=FB, NOASA will be used. If SYSPRINT has RECFM=FBA, then the ASA parameter will be used for the assemble. 

When allocating SYSPRINT to a file, use the RECFM to determine the assemble parameter you expect. See IBM ASMA90 documentation for details.
