Need help switching back and forth

[Bill819]

Hal will call or run another piece of software just fine. The question is that once I switch back to Hal is there a way to switch back again without running the program all over again? It would be like pressing Shift/Alt to change applications. Is there another way to do it in hal?
My robot is almost complete and I am trying to put the finishing touches on it.
Thanks
