I'd just like to clear up some of the clearing up ti-82 confusion :)


The program variables on the 82 are actually handled in a simpler way =
than the 85 does.  Since you must get everything from menus, you're =
right that the program is already tokenized.  The program never changes. =
 This makes programs a perfect variable to store the assembly language =
programs.  Also, TI-82 programs have a built-in feature to be edit =
locked, so that there's no way to look at the actual code on the 82.  =
This would be perfect for Assembly programs, which would be ugly to look =
at in a program.
	The rest of your mesasage is basically irrelevant ti-82 bashing.  The =
ti-82 has a wide number of users in many schools, and I'm sure making a =
zshell for it would be *very* popular, and worth our discussion time.
