Jump into a sub-code with GOSUB. Define a SUB with SUB mark: (Don’t leave the colon). End a SUB with ENDSUB. SUBs must be placed at the end of the main program. It’s not allowed to have code between ENDSUB
and SUB. A SUB can be leaved before ENDSUB by calling RETURN. You can call GOSUB from within another SUB. A good way to create new SUBs is the command “new SUB” from the Project menu.
Sample:
GOSUB draw SHOWSCREEN MOUSEWAIT END
SUB draw: PRINT “Eine Sub”, 100, 100 RETURN // Jump back to GOSUB
PRINT “You won’t see this!”, 100, 150 ENDSUB
