How about
LA 7,5 Put 7 in register 5
That'll confuse 'em!
(Just kidding.)

==> LA R7,5 Put 5 in register 7
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.
