there is a problems with that: if a program on interrupt is called
when memory is being modified the calc will crash...
so this method would only work for programs which wanted to install
intetrrupt routines to be used while the program is running - and you
may as weell use teh graphscreen for that...
not to mention it'll make zshell about 300bytes larger... (at least)
The best way of zshell to install interrupt routines would be for it
to expand itself and put teh prgrams code inside and install it on an
interrupt... I'll work on this!
