Now that we have debugged the function enough we do not want to step any further inside the function, but go ahead and debug the rest of the main program. You could in our example issue r 14, or better, well ... is it r 16? You have to list the lines, step in the stack up, find the next executable line and issue the command r.
Instead of that just issue the command o, to step out of the current function.

014. MyFunction a

>016. a = a + 2
017.
018. MyFunction a
As you see it still printed a character and stopped at the line 16.
