%Elem(Array) vs. cCMLimit

This isn't the most important question of our times, but I just wondered
what everyone else thought.

If I need to define more than one array, each array with the same number of
elements, I typically do this:

D cCMLimit        C                   20

D CM#             S              7  0 Dim(cCMLimit)
D IN#             S              7  0 Dim(cCMLimit)
D AMT             S              7  2 Dim(cCMLimit)

Then, later in my code, I always use the constant I created, like this:

For X = 1 To cCMLimit;
  <do something>
Endfor;

Or this:

If X <= cCMLimit;
  <do something>
Else;
  <do something else>
Endif;

It suddenly occurred to me that even though I used a constant to define the
size of the array, in the code I should still use %Elem like this:

For X = 1 To %Elem(CM#);
  <do something>
Endfor;

Because this makes it immediately apparent to any other programmer (or me 6
months down the road) that I'm traversing the entire array, whereas using a
constant doesn't imply that.

What do you think?
