Re: Deleting vars (TI-85)
There is no way to delete variables from within a program on the TI-85. What
you CAN do, though, is if the variables are algebraic (not pictures, GDBs,
etc.) just store a null string to them at the end of the program, like this:
""->A
A null variable with a one-letter name only takes 7 bytes of memory. I always
use one-letter variables in programs when possible, because this is very
common and it doesn't clutter up memory with a bunch of weird names that the
user has to delete when they want to remove a program from a calculator.
But don't use one-letter names for important stuff like saved games, though,
because it's likely that another program also uses the same variable for
something else.
