You would have to have a Case for each program and call the sub program like that. This of course makes the program Massive if you have lots of sub programs you may want to call. which may cause the Robot controller to slowdown or even fall over. (Its probably the most annoying feature with the UR Robot) I’ve already created a wish list pos for this feature > [@Separation of Sub programs from the main program](https://forum.universal-robots.com/t/separation-of-sub-programs-from-the-main-program/18684): > > Summary Sub programs currently get integrated into the main program. Having a large amount of sub programs integrated into the main program make the whole program very large. This has the effect of making the robot struggle to process all the necessary commands. It also makes the program script difficult to read. What is it? I would like to have them separate. Why is it needed? I have a Main program that calls individual sub programs based on some variables. to do different tasks. the pro… --- _[View the full topic](https://forum.universal-robots.com/t/call-subprog-with-string/24709)._
