RE: Subfile as a procedure

Peter's stuff looks very interesting. It does not, however, use the C routines. With the C routines you would not use F-specs hardly at all - all done in code. That is why RPG is so easy comparatively but also why you can't dynamically assign what format you want to use. C routines in RPG give us tremendous power and flexibility. Some I won't tell you cuz it's a secret!!! Well, not really, but it's part of what I want to use in our products someday. So I leave some as an exercise for the reader.

He does appear to use the DSM routines - maybe they let you dynamically set subfiles - that'd be another method. I have not looked at those, but for me the C routines are pretty intuitive - very analogous to the RPG opcodes - almost direct analogues. So they might be easier to work with. Not sure, however.

You may want to look at Peter Levy routines at
http://home.att.net/~peter.levy/Downloads.html I have played around
with them a few times, but haven't ever gotten around to rewriting any
of our production stuff using it.

Right - have used some of those functions in a previous life - thing is,
you can specify - in fact, you HAVE to specify - the format you want to
use, in a separate call, not in an F-spec, so its name can be passed as
a parameter to a generalized procedure. In RPG we are insulated from all
these gory details, but we do lose some power thereby.

Oh - one could also go with UIM panel group lists, too!

Just expanding on your info, Jon - heh!

Just the other day I was thinking along these same lines. My
thought was
that if I could soft code the record format in a variable I could
move my
subfile setup to a sub procedure and just pass the record format in

a

variable as the parameter that way I wouldn't have to write the same

subfile prep code over and over again for each one. Well as I found
out, ...

This can be done in RPG, but only by prototyping and wrappering the C
record I/O procedures. This is not that hard, but does require a
certain amount of knowledge of C. I thought that there were some
examples of doing this out on the web but I don't have time to search
for them right now.

An alternative option is the use the Dynamic Screen Manager (DSM) APIs

to handle the screens. This will not strictly speaking give you a
subfile but can be used for scrolling lists in windows etc. Again
there are examples out there.
