Execute a function block defined after :FUNC_NAME, returning to this position when done.

Notes:

• Functions use the same stack and variables as the rest of the script.
• This is useful for passing arguments.
• The :FUNC_NAME is essentially a marker for where the script should go when @FUNC_NAME is encountered.
• When a function finishes, the script keep executing from after the @FUNC_NAME that triggered it
