Why not post your test program code iso. of the re
Thanks for your reply. That clears it up for me. My bad for not rereading the
section on decimal codes at the beginning of Chapter 8 before posting my
question!

Does this guarantee the convention

Subject: Actual signs set by the DP (divide decimal) instruction
I am working on
I am working on z390 (Don Higgins' software) fixes to the emulation of the DP
(divide decimal) instruction and have a question as to what signs are set for
the remainder.
Normally I would answer my own question by running sample programs, but I am
retired and do not have access to a mainframe.
