1. RE: Return misplacing values?

Hi!

Thanks for the response and sorry it took so long for me to respond.    
Here are my actual routines and the ex.err.  I know that stateC doesn't 
grow out of the limits of an integer as GameState (which it is derived 
from) is only given constants that are 50000 as an upper limit.

This program isn't really that large but it is broken down into several
smaller code files.  It is big enough that it won't fit in a topica 
message though.... at least I think....

Thanks for taking a look, I really appreciate it. 

Sinc,

2. RE: Return misplacing values?

It looks like the error was produced by a CPU exemption handler. It's realy
hard to tell just what is going on but maybee Robert Craig could shed some
light on this. (since he would know what exemption handlers are installed
and for what reasons an exemption error might be produced).  Sorry that I
can't help you with a solution other than a CPU exemption has been caught.

Good luck I hope someone can help you further with a possible cause for the
exemption.
