   In the recent issue of Fig's Forth Dimensions, there is an article
discussing a 3 stack Forth implementation. I am not to sure, since I
don't have my copy around at work, what their uses are but I can follow
up on it. Also, in past issues of Forth Dimension, various author have
discussed mutiple stack usage and implementation including a string
stack and a stack of stacks.

I'll see what I can find....
