My method is not "foolproof", but to ensure against a casual mistake, I pass a hardcoded, lengthy parameter from PGMCL to PGMR, i.e.: In the CL: CALL PGMR PARM('Program PGMR can only be called from PGMCL!') In the RPG: I 'Program PGMR can onl-C @CLCHK I 'y be called from- I ' PGMCL!' C *ENTRY PLIST C PARM $CLCHK 50 C $CLCHK IFNE @CLCHK * THEN TAKE DESIRED COURSE OF ACTION... Most likely, no one will ever mistakenly call PGMR using the correct parameter.

Hi All, In one of our application, we have an RPG Program say PGMR which is called by a CL Program say PGMCL. If i want to ensure that PGMR is called by PGMCL alone and not directly from command line or from any other program, how will i check this in the called Program ie PGMR.. Thanx in advance Shepherd P Chacko Robert Bosch, India. +--- | This is the RPG/400 Mailing List! | To submit a new message, send your mail to RPG400-L@midrange.com. | To subscribe to this list send email to RPG400-L-SUB@midrange.com. | To unsubscribe from this list send email to RPG400-L-UNSUB@midrange.com. | Questions should be directed to the list owner/operator: david@midrange.com +---
