Wouldn't 6 (six) be better in R&? Five (5) seems pretty small. <g>

It depends on the intended target audience. Now I and you know that
a 5 is put in Register 7, but many shops have only a couple
Assembler Programmers....but many more Cobol programmers. Telling
"them" that a 5 is put in Register 7 can be helpful to solving a
problem or learning what a program does.
Way too many Cobol programmers that I run into are scared of looking
at Assembler...like just looking at it or trying to learn it is
going to give you Ebola...so even very basic instructions can be
helpful...especially if Instruction says LA 7,5 then it really helps "them".
Thanks,
Tom

Long ago in a galaxy far away, they handed each of us a stack of
manuals and told use that we were all enrolled in a 7070 class and
had to read all of the manuals before the class started. It turned
out that some of the students were answering questions that stumped
the instructor, and that if you read the manuals you didn't need the course.
The worst are the ones that score based on the quantity of comments
instead of their quality. That guaranties cluttered and unhelpful
comments. People will behave in such a fashion as to optimize how
their organization ranks them; if teir grades or performance reviews
depend on doing something sub-optimal, then that's what they'll do.
Measure the things that actually matter.
I generally frown on marking students down on stylistic issues like
labels on separate lines, but I will mark down for
LA R7,5 Put 5 in register 7
Don't tell me what LA does, tell me why you're putting that value in
that register. If there is nothing useful to say in the comment, then omit it.

Yes, I was taught that early. Then I took a Commodore SuperPet
assembler class (after writing 370 assembler for several years).
That assembler had no
DS 0H
but it did have
EQU *
So I used that-and was marked down for it. At that point, I stopped
taking the class seriously.
