I ran the tso command processor under TESTAUTH
When I get to the BR R14 of validity check rtn I inspect R14

Surely that's not the main reason you are calling IKJPARS...
The code in the routine runs ok
which routine - the validity check exit? You know for sure that it
ran?
however the problem I have is the with the
return address R14 seems to point to CVT field
CVTBSM2 offset 1DE in the CVT
Why is that a problem?. Did you restore all the non linkage registers
(2-13) before you branched to R14? From wherever you saved them on
entry to your validity check routine?
The following is the syntax of the call CALLTSSR
EP=IKJPARS,MF=(E,PPL) the
code picks up the address of the IKJPARS from CVT
and balrs to IKJPARS
OK.
setting R14 to CVTBSM2
I see nothing at all like this in the CALLTSSR macro on any of my
systems (z/OS 1.10 through 1.13). There are no references to CVTBSM2.
But it's IKJPARS that sets this value, not CALLTSSR.
Am I suppoused to return with a register other then r14
From the validity check routine? No - you are to return to the address
passed to you in R14. Did you save and restore all registers as you do
for any other program? In particular, the BSM 0,R2 requires that the
caller's R2 be restored. This is just returning to the caller's AMODE.
