Re: Subfile as a procedure

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.
