Great!!! 8)

Note: you can add FASTCALL to these subs, for a little optimization (in the future, 0 parameters & 0 local var functions and subs will be automatically fastcalled, but not at the moment)

I was about to make this as fastcall routines, but after all it is not necessary as they don't need to be called fast as possible (maybe just to save some memory?).
What you wrote about the future plans to make SUB/FUNCTION with no parameters automatically fastcalled, sounds great!
