Re: Global Variables Being Overwritten

BINGO! Thanks a million!

"Some suggestions:
- Check your stack placement. Make sure it's not colliding with data
space. "

My compiler automatically placed the stack right in the middle of my
data. The stack was set to 80 bytes. I reset the size to 255 bytes
and the compiler moved it out in the open away from my other data.
(Not an major issue, but still not sure how to specify the exact
placement of the stack with my compiler).

Now the stack has plenty of room to expand!

Thanks again!
