I see the point about using an array since it is passed by reference rather
then value. But I was thinking more along the lines of the amount of data
that can be passed to a variable. I believe the max size would be around
32k.

32k is the (old) maximum size for a single alphanumeric field in RPG. Today that limit is 64k.

However, it's not (and AFIAK, never has been) the maximum for an array. An array can potentially be as large as 16mb in size (actually, 1k less than that)

The record length I  will be using is around 250. If I need to return
say 500 records, that would put me way beyond that variable size limit. Does
using pointers allow me to access a greater amount of data?

500x250 = 125000 (approx 123k) you should have absolutely no problem passing that as an array.

And the code will be much nicer to read without the pointer logic. Just be careful to make sure that the array definition is the same in both the caller and callee. Use a /copy member with a prototype to enforce this.

Good luck!
