Check your Classic Desk Accessories menu, and turn "Alternate Display Mode" to
_on_. That, at least in my experience, will get rid of the 2s: your program is
trying to use the second text display page, which exists at $800.BFF and is
the same location as a normally-loaded Applesoft program.

Of course, the possibility also exists that your program's corrupted, and
trying to do something that shouldn't.
