@Raylin:
I tried appending >Char to Disp A; it just outputted an ñ (an n with a tilde).
Then I tried using >Tok (because I think the documentation mentioned something about tokens in the "input" entry), which returned a square then an x with a line over it.
I tried deleting and reinstalling a freshly downloaded version of Axe, but it did the same thing, plus now it appends an italic 'n' whenever I try typing in something, even after I recompiled.
On a tangent, is it possible to use 'input' on the graph screen instead of the homescreen?
