E-CodeArrow-key counter — a TI-84 Plus CE program
COUNTER is a TI-BASIC program for the TI-84 Plus CE. Counts up with the right arrow and down with the left. Press clear to stop.
How it's checked
It is run on the TI-BASIC interpreter by E-Code's automated library checks, which also check a computed answer where one is easy to state. It has no oracle case file, so this page gives no case count.
