A little experiment...works pretty well. Probably want to run in turbo speed if you want any kind of speed for your logic flow. INSTRUCTIONS: -Select tools at the bottom. -Clear clears all data (duh) -Begin will run your scripts until you hit Stop. TOOLS (from left to right): -addition -subtraction -multiplication -division -exponential -square -square root -sine -cosine -numerical control -numerical indicator -wire layer Logic flows from left to right always, so don't put a numerical control behind an operation and try to run a wire between them. Place all functions before you run any wires. To run wires, draw in the direction that the logic flows (i.e. numeric control -> addition, not the other way around). Press s while hovering over a numerical control to set it's value.
