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

Perhaps you should look into the CLP manuals.

Using group jobs gives you a GDA, length 512, to communicate date between jobs within the group. Did not know there are still used.

Best bet is to use the Retrieve Data area API. IIRC that works with *LDA and *GDA.

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 free-form
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?
