Of course there is. Its just so many are fans of the BGLOGIC stuff that I think they forget not all customers purchase this option.
Just do it as a short TPE program that loops over and over or do it in Karel in the same fashion.
SO..
at the top of your 'main' program, simply do a RUN 'program name' and it will run in the background setting your output while your main foreground program executes like it should. You don't want to use the CALL , use the RUN command.
Hope this helps..
