Allow direct coding of nested data structures in free-form declarations

The new free-form data declarations in RPG IV lend themselves to direct coding of true nested data structures. Allowing these to be coded directly would avoid having to code a lot of unnecessary templates that exist for no other reason than to nest data structures.

This would be particularly useful when defining the type of nested DS required for use by XML-INTO. The current method makes it very difficult to see the correlation between the DS definitions and the actual XML itself. By allowing the structures to be nested we could directly represent the structure being coded.


Use Case:

Instead of having to code this:

dcl-ds Invoices Qualified;
InvoiceCount int(5);
Invoice Dim(99) LikeDS(Invoice_T);
end-ds;

dcl-ds Invoice_T Template;
CustomerId Like(CustNo);
InvoiceNo Like(InvNo);
LineCount Int(5);
InvLine Dim(99) LikeDS(InvLine_T);
end-ds;

dcl-ds InvLine_T Template;
// invoice line details
end-ds;

We should be able to code:

dcl-ds Invoices Qualified;
InvoiceCount int(5);

dcl-ds Invoice Dim(99);
CustomerId Like(CustNo);
InvoiceNo Like(InvNo);
LineCount Int(5);

dcl-ds InvLine Dim(99);
// invoice line details
end-ds;

end-ds;

end-ds;

    IBM intends to provide a solution for a future release, and also to provide PTFs for 7.2 and 7.3 timed with a future Technology Refresh. However, IBM's plans may change and no commitment is made that a solution will be provided.

    .IBM will use this request as input to planning but no commitment is made or implied. This request will be updated in the future if IBM implements it. IBM will use votes and comments from others in the community to help prioritize this request.

    IBM has received the requirement and is evaluating it. IBM will provide a response after evaluation is complete.
