So, I have two appvars. One contains a long string of words - a string of strings. The other contains, in order, the location of each string relative to the string appvar's pointer. How can I display one of those strings if I have where its first letter is and where its last letter is? I'm having trouble with this...

I've been playing around with cellular automata for a few days or so, and I really want to create the most famous one, Conway's Game of Life, in Grammer. I know the language pretty well, I just need to know if it would be possible to have two scripts running at once or something. I need to have a script that calculates the alive and dead cells, and a script to move a cursor around which will be used to draw. I can't have the pixel on the graph when I test for the cells because the program would treat it as a live cell. I was thinking of turning on the pixel, showing the graph buffer, turning off the pixel, doing the script to recalculate positions, then repeating, but I don't know if that will serve my speed needs, since I want to be able to move the cursor between generations. Any other good suggestions?
