Hello,
I am looking for a mapping macro so as to avoid re-inventing the wheel. Pardon me if some fine manual has the answer. I actually looked in "DFSMS
Macro Instructions for Data Sets" but could not get something fruitful to go ahead.
Do you think there a DSECT macro that maps to VSAM ACB MACR1, MACR2, MACR3 and MACR4?
DSECT macro to map VSAM ACB.

Re: DSECT macro to map VSAM ACB.
Have you looked at IFGACB in SYS1.MODGEN?
Google is your friend -- I found this by Googling acb macro and it was one of the early hits.

Thanks Robert.
Looked at SYS1.MODGEN and then at SYS1.MACLIB. Just wondering why the macros are divided between these two libraries and why are not placed in one only?

Re: DSECT macro to map VSAM ACB.
historic reasons,
SYS1.MACLIB content was thought for normal programming tasks
SYS1.MODGEN constains SYSTEM programming related macros.
once upon time its content was not even <installed> on the running system
and system programmers were forced to use SYS1.AMODGEN - the distribution library
and more than often - disk space constraints - the distribution libraries were not <online> but backed up to tape
with a bit of trouble for the sysprogs who needed them
