Re: Subfile as a procedure

[vhamberg@xxxxxxxxxxx]

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!
