Re: 5250 data stream issue

Wouldn't this flow better if you started with program "S" which asked
the user what they wanted to do, then call "M" to do that work and
return to "S" which sends the user the status message? "M" would
never need to access the display file, only "S" would need to do
that. "M" could be reused from other places and as a batch job since
it never needs to interact with the user

It would if executing the operation specified in "S" were all that "M" did. Unfortunately, "M" is the core program of the application (extremely interactive, using both conventional display file records and a user-defined data stream), while "S" is simply an auxiliary prompting program for the one function.
