  POKE X+&H23, PEEK(X+&H23) OR 8

Nothing to fix here. The standard order of operations is what you want.

The problem with the S/SC code is that the standard order of operations
is not what we wanted.

  X AND Y = Z

The equal sign has a higher precidence than the AND operator. So it was
like saying:

  X AND (Y = Z)

So I had to force it using parenthesis:

  (X and Y) = Z
