Do not mark data structure or other container as unreferenced when any subfield is referenced

In recent releases of RDi, unreferenced variables and file declarations are marked with an information annotation.

If a data structure is not, in itself, referenced, it is so marked.

But any subfield that IS referenced is not marked.

I want the containing data structure NOT to be so marked when any of its subfields is referenced.

Here is an example of a PSDS, where the actual data structure will rarely be referencedas a whole but the JOBNBR subfield would definitely be referenced.

dcl-ds pgmStatDS psds;
jobNbr char(6) pos(264);
end-ds;

As for a file declaration, it might be marked as unreferenced even when the record format IS referenced.

Here is an example that involves a file, an I/O data structure, and the use of that data structure when writing to the record format:

dcl-f rphHrsSkp usage(*output);
dcl-ds outHrsSkp extname('RPHHRSSKP' : *output) qualified inz end-ds;

eval-corr outHrsSkp = lRphHrs;
write rlRphHrsSk outHrsSkp;

The dcl-f is marked as unreferenced, but when I comment it out, the write statement fails with a couple "not defined" messages (RNF7503 & RNF7030).


Use Case:

These annotations that indicate when a "container" is itself not referenced are confusing and can lead to unnecessary work, if a developer removes the "unreferenced" item and compiles, just to find that the compile fails.

    The feature that is described in this request is a candidate for a future release.

    Although the theme of this request is consistent with our business strategy, it is not committed to the release that is currently under development.

    I have experienced another situation.

    Given the same data structures described below:

    In the code you have
    eval tmpTheDS.field2 = 123456
    but field2 in theDS is marked as unreferenced.

    If I want to clean up my source and delete the line with field2
    then I have a compile error because it now no longer exists in
    the tmpTheDS data structure.

    I have experienced that if you have a situation like this:

    theDS is a qualified data structure with fields field1, field2 and field3
    tmpTheDS is a data structure defined using likeds( theDS )

    in the program tmpTheDS is referenced
    eval tmpTheDS = theDS
    eval tmpTheDS.field2 = 123456

    then tmpTheDS is marked as not referenced for some reason.

    ( I'm using RDI 9.6.0.3 )
