If you have a procedurial language and you have multiple exit points from a procedure, and then you want to do some "exit" actions, you could do the same trick as you would with an OO language. You mask the procedure by another one, that calls your original procedure, and then does the exit actions. Except that with an OO language, you typically create a new class that calls a procedure with the same name in the original class, but with a procedural language, you rename the original procedure, and create a new procedure with the original name, that calls the original procedure, and then does the exit actions. Same technique, different syntactical details.
