Re: RPGLE Return vs *INLR

Kevin, are you trying to fix a bug, design a solution, or understand a conundrum?

Is my understanding correct; all of the programs were created with DFTACRGRP(*NO) ACTGRP(*CALLER)? Assuming Program A was initiated from a menu  in the *DFTACTGRP, then they all have their resources - in particular working storage - in the *DFTACTGRP - correct?. Others have pointed out this is not ideal. However, putting this aside you asked.

1). If we call ProgramA and it makes it to ProgramD.  Let’s say LastClient = ‘AS’.  Then goes back to the menu. Then, from same session/job we call ProgramA again and it makes it to ProgramD. Will LastClient still have ‘AS’ upon entry?

A). Difficult to say. Is LastClient a parameter, using STATIC storage, part of a Data Structure based on an external Data Area? Are the programs using subprocedures? Is RCLRSC being employed? If none of these situations are apparent, then I would suggest the answer to your question is "yes".

2). If ProgramB has LastClient field. If ProgramB changes LastClient value. Will that new value be carried in to ProgramC and ProgramD?

A). Again, depends on how LastField is defined. But assuming the same conditions as 1). above, I would suggest "no".

This is a HUGE simplification; with traditional, non-ILE coding:
- RETURN with LR *OFF - leaves variables intact
- RETURN with LR *ON - causes variables to be "cleared"
- End of Program with LR *ON - causes variable to be "cleared"

CAVEAT: This assumes I've understood the question correctly! Bottom Line: Set up a simple test case and try it out for yourself to prove it. The situation you describe would be quick and easy to construct.

HTH,
Brian.

If I have the following:

ProgramA ends with *INLR = *ON

ProgramB ends with *INLR = *ON

ProgramC ends with RETURN

ProgramD ends with RETRUN



If program C and D have some Last Changed values like LastClient. No INZ
value on it in program C and D.



First question:

If we call ProgramA and it makes it to ProgramD. Let’s say LastClient =
‘AS’. Then goes back to the menu.

Then, from same session/job we call ProgramA again and it makes it to
ProgramD. Will LastClient still have ‘AS’ upon entry?



Second question:

If ProgramB has LastClient field. If ProgramB changes LastClient value.
Will that new value be carried in to ProgramC and ProgramD?
