The auth assembler services guide has the following:
GPR 2 Contains the address of the 24-byte parameter area returned by the
SETFRR macro when you specified PARMAD.
The IEAMSCHD macro has a keyword to set an FRR, but I don't see any
mechanism for passing a parm to the FRR.
Currently the way my code is written, the SRB does a SETFRR as
early as possible after beginning execution. It then places an address
in the parm area returned by the SETFRR, for the FRR to use if an abend
occurs in the SRB routine.
To test my recovery logic, I set up situations that cause the SRB
to either time out, or abend. On restart after the recovery, the next
time thru the logic to schedule the SRB again, I had an error that
caused an 0C4 at the front of the SRB logic, before the SETFRR was
excuted. And since the IEAMSCHD coded SYNCH=NO, I had no indication in
my code that the SRB had abended after being scheduled. Eventually it
was logrec that told me what was going on.
The FRR logic is used by all SRBs, and it is the parm that is
passed to the FRR that gives the FRR logic its 'context'.
Is there a way to pass the FRR a parm when it is created by IEAMSCHD?
