Is there an easy way to check to see if a user is member of a group within a CL?

I want to check to see if a user is a member of a specific group -- but wasn't sure how exactly to do this.

Any help would be much appreciated.

Thanks!

Here's a rough example:

DCL &PRIGRP *CHAR 10
DCL &SUPGRP *CHAR 150
DCL &GROUP *CHAR 10 value('QSECOFR')
RTVUSRPRF USRPRF(SOMEUSER) GRPPGM(&GROUP)  SUPGRPPRF(&SUPPLEMENTAL)
IF ((&PRIGRP *EQ &MEMBER) *OR (%SCAN(&GROUP &SUPGRP *NE 0))) THEN DO
...

One note:  &SUPGRP is one big long string containing up to 15 supplemental group profiles.  Each profile starts in a fixed position:  position1, position 11, position 21, etc.  It is technically possible to get a false positive:

Group = 'APR'
Supgrp = 'PROFILE00APROFILE00BPROFILE00C'

%SCAN would find APR in position 10.

So you'll need to get a little fancier in production code: maybe write a little loop that extracts 10 bytes at a time and tests them, or test the position returned by %SCAN to verify that it ends in a "1".
