I'm looking for some help re loops within a program. Here's the scenario:

A few steps into a program the 48GX performs a long mathematical procedure. Several steps later I want it to perform the same procedure using new numbers by looping back through it. How do I do this?

As a simple example:

1, 2, 3, 4, 5 and 6 are stored as a, b, c, d, e and f. How do I get the program to add a,b and c, then add d,e and f using a loop?

Thanks.
