Re: A86: Simple TI-85 Question
if you want speed, don't go for rom routines. using page $d adds 10/27
clocks.
the bit mask (fp bits, at $24e8 in 1.2) is used in a routine that finds a
bit in _FORMULA_BITMAP
$4967 find a bit in _FORMULA_BITMAP
$496B find a bit in (hl)
a = bit #
returns:
a = mask
(hl) = byte
this is not a findpixel routine.
the mask isn't used anywhere else on page 0
