It may be a little bit faster. You can check that by simulate the GOSUB 
with some GOTOs and compare the speed with a similar function call.

Anyway, there is a syntax problem. In Basic, GOSUB is ended by a RETURN 
instruction, but RETURN is already used to exit the all function. Or 
maybe RETURN will return from the function only if there is no pending 
GOSUB.

Can you test if there is any speed gain I as said above? I don't have 
the time to do that now. If the speed gain is worth it, then I may 
implement GOSUB!
