RE: Alternatives to MOVEL - just curious

Of course, in either of these examples, you would explain in comments
exactly why you were doing this, wouldn't you?
(I haven't met anybody who would deny this - so it's a mystery to me
where all this uncommented code comes from!)

I think the %div documents the intention better. Reason is that if I go
in to look at a program and am looking at the code itself then it isn't
obvious that the two fields are related unless you go find there
definition in the data structure.

For instance, if you have two lines of code.

Num6 = something();
Somethingelse(num4);

Just looking at that I start wondering where did num4 come from and have
to go searching where if you have the following it is easier for me to
understand right away.

Num6 = something();
Somethingelse(%div(num6:100));

If you spend a lot of time looking at code just to answer a simple
question about what it does in certain circumstances then you may only
look at a little bit of the code and it makes it easier to me at least
to not have to go looking elsewhere to understand it.

I agree with everything John says, but
I do prefer the DS because I think it
documents the intention better . . .

What I always do for these is %DIV:

num4 = %div(num6:100);

(Or %rem for the cases where you want a MOVE.)

To me, this is simpler than a data structure because it saves lines of
D-specs. However, I don't think anything will perform faster than a
data structure, because that requires essentially no (execution)
overhead at all, not even a move. In most cases, %DIV is plenty fast
enough.
