Re: A85: Shell Switching/Multiple Shells on same calc
I had this idea last year, but I never got around to doing it. To see
what I had planned goto
http://www.ticalc.org/mailarchive/assembly-85/1997_August/msg00056.html.
I just getting around to designing the architechure. I am interested,
though, in your TI-BASIC prgms. What and how did you do it. If you
would like to work together on this OS e-mail me back.
