Re: Data Arrays

[D.BALE@xxxxxxxxxxxxx]

Bob, Gord,

I tossed Gord's original email, because I've only breifly touched on the
subject before and I'm totally swamped today and figured someone else would
contribute...

So, just quickly, I got the impression from the original post that what Gord
was looking for was more along the lines was an array that defined subfields
of a data structure using the OVERLAY keyword, i.e.:

   D DataStruct      DS
   D   A                           10    DIM(5)
   D     B                          5    OVERLAY(A)
   D     C                          5    OVERLAY(A:6)

This is RPG-IV only, no RPG-III.  The nice feature about this is that you can
sort the array on any subfield (forget how, someone else???)

Anyway, I've always felt that multiple occurence data structures were a real
PITA, regardless of the RPG flavor.  I have used them, but usually not without
some brain strain involved.

Gord, check out the multiple occurrence data structure. You can probably
get what you want using it and the OCUR  opcode in RPG III or OCCURS on the
D-spec and OCCUR in RPG IV. Which RPG class did you attend? The S6109 RPG
IV class from IBM includes a topic on how to do this.
