Re: interactive msg subfile

In my programs where I have done the same thing as you are doing, the
PGMNAMQ is the main program (I set this variable value in the mainline
of the program with the *PROC value of the Program Status Data
Structure.) And I set the SND_StkCnt = 0.

So when the sendmessage sub proc runs it is pointing the the call stack
entry of the main program and the relative stack count of the message
queue is 0 (i.e. the message queue of the main program).

So I don't like these, but thats a different story.

I am required to put them in my interactive pgm.

Other developers write the following call to the SendMessage in their
interactive pgm using a subroutine.
I like procedures, so I put mine in a procedure. This is the ONLY

thing i

can see different between theirs and mine, but mine will NOT display

the

message in the msg subfile at the bottom of the screen. If you view

the

joblog, you see it there.
The snd_stkCnt is being set to 0, and I suspect this is what is

tripping me

up. Due to the fact that it is in a procedure ("mini pgm") instead of

a

subroutine, the stack count is wrong. I tried setting to 1 with no

luck.

Can anyone shed some light on this?

The above suggestions are all appropriate, but the first thing I always
check is for the OVERLAY keyword. If you write the SFLCTL record for the
message subfile control record first, the OVERLAY keyword needs to be on
your main record on the display. If you write the message subfile control
record last, the OVERLAY keyword needs to be on the message subfile
control record.

If the above is correct, then look at the message in the job log and
display the message details. (Put your cursor on the message, press F1,
and then F9.) Check what is shown for the 'To program' and 'To procedure.'
Based on what you find here, you can use any of the methods from previous
posts to adjust, as needed, where the message is sent.
