When control is returned to Pgm A, value is in
occurrence 50 of the MODS.
When you pass a MODS as a prototyped parameter, it passes the current
occurrence. (As you've seen.)
I assume you didn't add the DIM keyword for the prototyped, so I think
it makes sense that it would pass the current occurrence.
Just by the way, if you use an array of data structures (DIM keyword
instead of OCCURS keyword), you can distinguish between the whole array
ARR, and an element ARR(i).
For sure I would recommend using a DS array for new code, since it's
easier (I think) to code array indexes than to manage occurrences.
But for existing code, it's not usually easy to change a MODS to a
DS-array, since it involves changing every reference to the subfields.
For example, if a MODS named INFO was previously not qualified, and INFO
was changed to a qualified ds array, the reference to subfield ADDR
would change from simply ADDR to INFO(index).ADDR.
