Yeah, of course it'll do that!

Every calc that uses a file name for variable will NOT allow you use commands
or functions as the name of any variable. This is because the calc can't
differentiate a command or a file name if they are identical. To keep the calc
from locking up, TI made a routine that essentialy traps you by givving an
error message, so the mistake is not made. If you could, your calc would lock
if you typed the command!!!

Try it on any calc! Believe me! The same ought to be true with any programing
language such as C or BASIC or Pascal or anything Variable names can't be the
same as a command name! A Mac, and a few other computers will allow a file
name to be identical to command names because they don't have a built in text
based commands, however I doubt you can name a file identicaly to a system
file on a PC.

It's just a limitation of most programable devices.

It's actualy not a bug! It is to actualy protect you from a REAL crash, by
warning you you can't do that.
