That's fine. Watch your bank select bits, though. They call it "move", but
it is indeed copy. It does not delete the value from w. If it were to
delete it, what would it put there? The mov instruction is common to
pretty much every assembly language I'm familiar with. It indeed copies
the contents of one location to another (or in the case of movlw, copies
the literal into w).
