I agree with this as well.  If you don't want the 9999 limit, don't use
a MODS.  Just use a based data structure and pointer arithmetic.
This is so easy to do on the V4Rx versions that you might as well!

(I used to do this on V3R2, using user spaces and a home-written
"offsetptr" routine because I didn't have the ALLOC op-code or the
ability to do direct pointer math, but needed a larger MODS)

The use of the OCCUR op-code is awkward to say the least.  Why bother
with it?

That's true.  A lot of RPG programmers will go and run and hide under 
the bed when they hear the word "pointer".   It's too bad...   But if
we keep trying, eventually we'll get them to accept things like pointers,
procedures, and the discovery of fire...
