Mike,
If you don't want to muck about with the existing api/procedure
A technique I've used is -- in your RPG program, you can --
set a global error indicator in the subprocedure and test
it's value from the mainline code after the subproc call to see
if the subproc is signaling an error, and subsequently, do the
call to display your message from the mainline code.
<d-specs>
gError
gErrorMsg
</d-specs>
<mainline>
// edit field
Proc1(anyfield)
If gError
// call pgm/api that sends msg to line 24
SendMsg(gErrorMsg)
endif
</mainline>
<proc1> (1 parm in, return nothing)
If yadda yadda
// theres an error
gError = *on
gErrorMsg = 'You have an error.'
endif
</proc1>

Jerry's on the nose with the call stack parameter. There was recently a
discussion about this API where I had posted a sample prototype that may
or may not be helpful:

The message refers to a program in the stack, but the stack also
includes procedures.

G#AddMsg is, I'm guessing, using the QMHSNDPM API. I still use
subroutines for the process you describe, but one of the parms for
QMHSNDPM (I forget which one) has to do with where on the call stack or
such the message is sent. Check the API documentation and modify the
G#AddMsg subprocedure accordingly.

Subject: Subprocedure global/local ?
I am trying to make myself use subprocedures more- rather than
subroutines. I have run into a little problem, and I'm not quite sure
what I need to do.
I have a procedure in a service program that is used for displaying
messages in display files. I use this all the time.
Now I have written a data entry program that has quite a bit of
validation. I have written another service program that has the
validation in it. Because there is a lot of validation I put all of
these within a subprocedure in my main program. Here is where the
problem occurs. My messages don't display. If I simply change the
subprocedure to a subroutine, my messages display.
PGM1
CALLP checkvalid
Pr checkvalid
C Eval PaverErr = valid_paver(cscrew)
C If PaverErr = *On
C Move 'RG1010 ' MSGID
C CallP G#AddMsgSF(MSGID:' ':
C 'RGCMSGF')
C EndIf
G#ADDMSGSF is in service program
Valid_paver is in a separate service program.
Checkvalid is subprocedure in main pgm
Any ideas on how to make this work.
Mike
