Re: What am I missing, or free-form data structures and the group data area.

Yeah I found references to it...

But nothing about how to access it from RPG.

The RPG manuals just talks about the LDA and PDA...

I'd have free form be a standard rather than using GDAs.

Interesting...in 20 years...never heard of a Group Data Area...

Neither the RPG/400 nor RPG IV manuals mention it.

How do you define it in fixed format?

Unless I have missed something, I have found a deficiency in the

data structure definition.

If I want to use the local data area, mapped to a data structure

defined by

an external (reference) file (e.g. LDA),
my declaration would look like:

Dcl-DS lda Ext DtaAra(*LDA) End-DS

No problem. But I can't do the same for the group data area (which

our

menu

system uses).

Dcl-DS gda Ext DtaAra(*GDA) End-DS

generates an RNF3343, which says only *LDA and *PDA are valid.

Have I found something free-from can't do (makes it sort of hard to

argue

free-form should be the standard), or am I missing something?
