My guess is that you are doing something wrong. Probably
making assumptions about your variables that aren't
correct--this is the most common reason for these
kinds of problems.

In any case, WE can't help you here. When your program
crashes, why don't you just take a look around? What is
I at that point? What is j? Are the variables you are
trying to subscript big enough to accommodate I and j?
The HELP command is, uh, well, helpful in figuring
these kinds of things out.

The error message indicates that either I or j are
bigger than you think they are, or your data
arrays are not the size you think they are. Only
you can tell us this. :-)

Cheers,

David
