Re: RPG400-L Digest V2 #357 -- RPG400-L

Thanks Richard, Martin.

When I used debug to add a watch I got:

Num      Variable                 Address              Length
1        $PGM                     F9BAF3B174017730     10

At the same time I used the following command in debug:

%ADDR($PGM) = SPP:F9BAF3B174017730

Then I did the DMPJOBINT followed by PRTINTDTA and found what I assume are
the stack entries for the program I was debugging (MOUSER):

ISF ADDRESS   C8C645783F FFBAA0       TYPE MI PROC
    RESUMEPOINT     3A80CC5AED 001AE4     ENTRY@    3A80CC5AED 001940
     PROGRAM  MOUSER
     ENTRY    MOUSER + 000001A4
ISF ADDRESS   C8C645783F FFBC20       TYPE MI PEP
    RESUMEPOINT     3A80CC5AED 0018AC     ENTRY@    3A80CC5AED 001790
     PROGRAM  MOUSER
     ENTRY    _QRNP_PEP_MOUSER + 0000011C

Scanning the dump output for C8C645783F FFBC20 I found (among other things):

ISF ADDRESS   C8C645783F FFBC20       TYPE MI PEP
    RESUMEPOINT     3A80CC5AED 0018AC     ENTRY@    3A80CC5AED 001790
     PROGRAM  MOUSER
     ENTRY    _QRNP_PEP_MOUSER + 0000011C

I could keep going -- I found some references to F9BAF3B174017730, but
nothing conclusive. However, it does sort of look like %addr(variable) is
the address that we want to be aligned. I haven't heard anyone contradict
that. If true, you could programmtically determine if your data structures
are aligned.
