GOTO inside a function question?

[RandomiserUsr]

I have two functions that have a return 0 

Code:

FUNCTION processTest(test INTEGER) as INTEGER

......processing stuff

IF X=1 THEN
   poke TestAddress, 1
   GOTO displayMsg
END IF

return 0
END FUNCTION

Does the this cause any memory leaks on the stack?
i.e. by not "returning" something is left on the stack and won't be removed?

I remember something about GOSUB/RETURN having this or am I okay to not RETURN (I am experimenting before you may say it's not "good practice      )


Thanks in advance

okay so having changed the code around and no not jumping from a function with a GOTO rather than RETURN, the out of memory errors I was getting have gone.
