that's a good idea. maybe store
the real number where the first digit
in the number (the exponent doesn't
matter) is the row while the
second and third digits in
the next two bcd memory areas
constitute the columns.

so to put the number on row
2, column 15:
:215->A
:Asm(PutRAM)
which would be the same
as
:2.15->A
or
:21.5->A
because we won't be looking
at the exponent (that
$fc00) thing, but instead
move straight
to the bcd digits.

the first nibble is
the row, the second
and third nibbles
are the columns.

that might work? what do
you think?
