It occurred to me after I sent it that I could do the same thing with a
pointer without having to move the bytes. Had to remove the CONST on the
input because you can''t take the address of a CONST..

ctl-opt Main(TestIt);
dcl-pr Testit ExtPgm('TESTCMD1');
PR_InList LikeDs(TD_List);

dcl-ds TD_List Qualified;
FullList Char(1024);
NumberOfEntries Int(5) Overlay(FullList);
Offsets Int(5) Dim(10) Overlay(FullList:*Next);

dcl-s Qty Packed(11:2);
For x = 1 To InList.NumberOfEntries;
PtrItem = %Addr(Inlist.FullList) + InList.Offsets(x);
// Process Item
Qty += Item.BoxQty;
EndFor;
Return;
end-proc;

PM:
Does anyone have an RPGLE example of processing this type of a listwhere
there can be multiple entries?
You just have to use a BASED data structure and a little pointer
arithmetic. I've done it in CL (with *PTR and DEFINED using %ADDR and
%OFFSET) -- not in RPG -- but the concept is the same.
