Example:
Move f
[ label ] MOVF f,d
0  f  127
d  [0,1]
(f)  (dest)
Z
The contents of register f is
moved to a destination dependent
upon the status of d. If d = 0,
destination is W register. 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.
