Oh, this was BAL on a 360-44. This machine did not have
storage-to-storage
operations, everything was load/store registers. Moreover, the
routine
was
written by the "Systems" section - supposedly the best programmers in
the
shop.

There was blood in the corridors and owl feathers everywhere.



No MVC instruction???

You meant to say MVCL instruction.


Nope. Unless the 360/44 was really different, it had an MVC: move
characters. That's storage-to-storage. That was my point.

Normally, the Model 44 uses an abridged set of System/360
instructions -- those associated with scientific operations. It can,
however, with the addition of an Extended Instruction Set
capability run programs interchangeably with Models 30, 40, 50,
65 and 75 if system configurations (memory capacity and
peripheral devices) are comparable and the problem programs
not time dependent.

Months later, the 44 OS was made available, which was basically
360 DOS, rewritten for the 44 instruction set (which lacked the
commercially oriented "SS" instructions).

360/44 - the oddest model. It could be described as a 40 with a
hardware floating point processor and faster memory. ...
It had only 1/2 word and 1 word instructions and could therefore
use a one word memory width without any speed penalty. Due to
the odd instruction set, it had its own operating system, PS/44.
