Re: How to do qualified?

["Bill Hopkins" <BHopkins@xxxxxxxxxxxxxxxxxxx>]

Thanks Hans 

"functionality is new to V5R2" that gets me because I'm v5r1. Oh well I'll 
just wait.

Thanks

In other words, you want to code an "array data structure", right? 
The syntax for that is:

D FXQS         DS           qualified DIM(10)
D   WQTYN             15S 0

and subfields of the DS can then be referred to like 
"FXQS(X).WQTYN". But such functionality is new to V5R2. An "array 
data structure" is sort of like a "multiple-occurrence data 
structure", but the index must be explicitly coded, and the DS must 
be a qualified DS.

BTW, another of the V5R2 changes is that you can define a subfield 
of a qualified data structure with keyword LIKEDS. That is, 
subfields themselves can also be data structures or even array data 
structures! Coding nested array data structures within array data 
structures gives you the ability to code something that looks just 
like multi-dimensional arrays.

Cheers!
