You don't need the 'goto skipper' or the :skipper jump point. Example:
Instead of this:
if ($left($1,1) == /) || ($left($1,1) == !) || ($left($1,1) == .) { goto skipper }
Use this:
if ($left($1,1) == /) || ($left($1,1) == !) || ($left($1,1) == .) { return }
The 'return' alias allows you to exit out of a function without halting things, only skipping the rest of the code if the if-then-else statement is TRUE. Enjoy! :)
