RE: Basing a field on an unreferenced field(s) doesn't work

Buck, and Barbara,

Putting in
H debug
Did fix it.  Now all the fields, and all the array elements have the proper
values.

Under certain circumstances, the compiler will allow you to access an
"unreferenced" field from an input file; I don't know all the
ramifications,
but specifying DEBUG(*YES) on the control specification (1 in column 15 for
RPG III) will cause the compiler to populate every input field, not just
the
"referenced" ones.  As Barbara so elegantly put it, the I specs are
fundamentally MOVE instructions.  In normal (non DEBUG) operation the
compiler doesn't do the MOVEs for unreferenced input fields.

Ramifications I know of:
o DUMP will dump the value of all fields, including unreferenced input
fields.
o Performance degrades because of the additional MOVES for each input
operation.
o One can see all the input fields during a debug session.

I did not look at DUMP(A) yet.
