From: "Barry Erick" 
Subject: Re: Subs vs gosub:which is faster
 
The gosub is faster because:
 1) No long call
 2) No parameters pushed on the stack
 3) No dummy parameters pushed on the stack  (PB's 16 parameters are
     always pushed on the stack weather you use them all or not
 4) No parameters popped of the stack when in the sub
 5) no dummy parameters popped off the stack
 6) no far return
