We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope. |

The ClrHome command clears the home screen — not the I/O screen where the result of commands like Disp or Output is displayed (you'd need ClrIO for that), but the screen where you run programs and evaluate expressions. This isn't usually something you want a program to clear, so this isn't a very exciting command.
It also has the drawback that the ClrHome command itself (or the program it's used in) is displayed on the home screen after it is cleared, so the end result is not a blank screen but something like what you see in the screenshot to the right.
Finally, ClrHome cannot be used inside a function, because functions aren't allowed to modify the state of the calculator.
Error Conditions
450 - Invalid in a function or current expression happens when ClrHome is used inside a function.
