RE: Checking Calling Program!!!!

[Mark Walter <mwalter@xxxxxxxxxx>]

Make PGMR and PGMCL modules and bind them into one Program calling them 
PGMCL. That way there will be no PGMR to call. Only the module object will 
exist on the system.

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
