After I use the above routine in my code, I get a GPF in the marked
area. It won't GPF the first time it hits the marked code area, but
it will interate the inner loop about 40 (actual number depends on
phase of the moons) times, then GPFs. Am I dereferencing the
array/struct wrong? Please help, this thing is killing me :)

The code compiled error free.

Thanks
