Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

If I have a subroutine and I want to exit early, does it matter if I use end sub or exit sub to do so?

SUB STUFF
IF A = 0 THEN
A = A + 1
B = C * 8
END SUB <<<<< THIS LINE
END IF
C = 3
PIN(6) = 1
END SUB

THANKS!

from the manual

[quote] END SUB
Marks the end of a user defined subroutine. See the SUB command.

Each sub must have one and only one matching END SUB statement. Use EXIT SUB if you need to return from a subroutine from within its body.
