xx Default/reset defined characters
« Thread started on: Dec 10th, 2013, 3:29pm »
VDU 23 defines 8x8 characters and A%=10:CALL &FFF1 reads the current character definitions.
Is there a way to reset the characters, or to read the default character definition? (The equivalent of *FX20/*FX25 in Acorn MOS)

!440 returns a pointer to the user-defined character flags so you can 'undefine' a character by doing:

Code:
?(!440 + c%) = 0
