RE: RPG IV Performance

 >> I assert that the code part of the rpg4 program is probably shorter
than the code part for rpg3 programs.

Barbara or Hans can supply a more definitive answer but I believe the
reverse of what you suggest is true.  MI instructions are as you know of
the "Move Universe from A to B type".  W-code are of the "Move atom from
area A to area B.  If more atoms remain at A repeat." type.  The result is
that the actual instruction stream is significantly longer.  This would
also explain why you see far less difference when observability is removed.
