Re: [colorforth] Address STack

["Roger Levy" <trip_n_save@xxxxxxxxxxx>]

I'm with Chuck. In my opinion there's no point to focusing on the address 
register. If i'm not mistaken the only reason it was introduced was for 
hardware reasons ( @ in hardware is actually !A A@ correct? ) and the only 
reason there are many partical operations was just to not waste it. Since it 
was a compromise, and barely essential, we should just use it wisely. 
Chuck's worked diligently to balance his system. Add something without 
knowing it and there is a chance we could end up making it tip for 
ourselves.

Regardless, Chris: since it should only take a few lines of code, maybe you 
could try your idea out in a few of your apps and then tell us how your 
impression of it was?

I'd be curious.

Roger
