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!

You want to look for a thing called a 'linker command file'. If you're lucky the extension will be documented. If you're _really_ lucky about 30% of the syntax will be documented. After that you're on your own. Usually these have a way of locating segments -- you need to figure out how to tell it not to let data and stack collide.
