GLOP

"Consider a program — any program; let us call it GLOP. We begin designing our program by imagining that we have a machine with a hardware instruction that will perform GLOP (an idea that is not beyond the realm of possibility with today's microprogrammable computers) Thus, to write program GLOP, we merely write the instruction
GLOP
and we are done! Not only are we finished, but we are relatively certain that the resulting program is correct — assuming that the hardware primitive GLOP performs correctly (and if it doesn't, we can always blame it on the vendor)."
