TIB: Re: TI-Basic Digest V1 #468
maybe just switch my program to store both variables into real number values
and then compare those?

I tried this on my 86 and it doesn't work.
This is because once a key is pressed, the calc's getky will store the
keypress to the Ans var. Then when another getky is called, it doesn't
recognize a key that's held down, so the key's status is reset to off, as if
no key is being pressed at all.
