Engineering toolkit hub — a TI-84 Plus CE program

By E-Code · updated 2026-09-26

ETOOLS is a TI-BASIC program for the TI-84 Plus CE. One menu that runs all nine tools above through prgm calls, keeps a session log, and summarises it on exit.

How it's checked

It is checked by E-Code's engineering suite: scripted runs on the TI-BASIC interpreter whose expected numbers were worked out separately in Python. It has no oracle case file, so this page gives no case count.
