<Another question about "why" (not "what is it doing").
<Why use a MOVE opcode when initializing a numeric field as opposed to the
<more clearly numeric-only Z-ADD opcode?
<The question is motivated towards understanding what the historical bias
<was, in terms of choosing MOVE instead of Z-ADD.
At the time it may have been thought faster to MOVE, (map bytes right to
left) than a Z-ADD, (set variable to zero then add zero). Performance was
more of a consideration in the S/34 days.
