This is from zshell40.hlp, written by Jeff Altman. If you don't have
that file, download it from ticalc.org, I find it verey useful.

Normal Text Operations
set 3,(IY+05) = Display white on black
res 3,(IY+05) = Display black on white (normal)
set 1,(IY+0D) = Alter text memory
res 1,(IY+0D) = Don't alter text memory

Menu Text Operations
res 1,(IY+05) = Print only 6 rows of the character
set 1,(IY+05) = Print entire 7 rows of the character
res 3,(IY+05) = Print character over current screen
set 3,(IY+05) = XOR character with current screen
