Re: OVERLAY with nested data structure

Uh oh. I played with it some more, and it seems the "qualified" was the
invalid syntax. Once I removed "qualified" the compile proceeded. Sorry.

Was:

dcl-ds FullName qualified overlay(TtlSiz);

Should be:

dcl-ds FullName overlay(TtlSiz);

I'm trying out the new i7.3 TR2 stuff. I have a data structure like the

following that I'm trying to convert to nested, but I'm not allowed to

use

the overlay in a datastructure definition. I've pasted the error message

in the "Desired State" section below. Is there a way around this? This
example only shows one nested element, but my production program has
several. They were removed to simplify the example.


Current state:
dcl-ds CD_t qualified template;
Col like(CurCol_t);
Wid like(ColWid_t);
Hdg1 like(ColHdr_t);
Hdg2 like(ColHdr_t);
end-ds;

dcl-ds FullName1CD_t qualified template;
Col like(CurCol_t) INZ;
Wid like(ColWid_t) inz(46);
Hdg1 like(ColHdr_t) inz('');
Hdg2 like(ColHdr_t) inz('Employee');
end-ds;

dcl-ds T1 qualified;
TtlSiz;
FullName likeds(FullName1CD_t) inz(*likeds) overlay(TtlSiz);

arr likeds(CD_t) dim(T1Cnt) pos(1);
end-ds;

dcl-c T1Cnt %div(%size(T1.TtlSiz):%size(CD_t));


Desired State that gives the error:
dcl-ds CD_t qualified template;
Col like(CurCol_t);
Wid like(ColWid_t);
Hdg1 like(ColHdr_t);
Hdg2 like(ColHdr_t);
end-ds;

dcl-ds T1 qualified;
TtlSiz;
dcl-ds FullName qualified overlay(TtlSiz);
RNF0202: KEYWORD NOT ALLOWED FOR A NESTED DATA STRUCTURE SUBFIELD
Col like(CurCol_t) INZ;
Wid like(ColWid_t) inz(46);
Hdg1 like(ColHdr_t) inz('');
Hdg2 like(ColHdr_t) inz('Employee');
end-ds;
arr likeds(CD_t) dim(T1Cnt) pos(1);
end-ds;

dcl-c T1Cnt %div(%size(T1.TtlSiz):%size(CD_t));
