the W register. If 'd' is 1 the result is
placed back in register 'f'.

The contents of register f is moved to
a destination dependant upon the sta-
tus of d. If d = 0, destination is W reg-
ister. If d = 1, the destination is file
register f itself. d = 1 is useful to test a
file register since status flag Z is
affected.
