In computer engineering and in programming language implementations, a stack machine is a real or emulated computer that uses a pushdown stack rather than individual machine registers to evaluate each sub-expression in the program. A stack computer is programmed with a reverse Polish notation instruction set.
The common alternative to stack machines are register machines, in which each instruction explicitly names the specific registers to use for operand and result values.

Famous quotes containing the words stack and/or machine:
“What is a farm but a mute gospel? The chaff and the wheat, weeds and plants, blight, rain, insects, sun—it is a sacred emblem from the first furrow of spring to the last stack which the snow of winter overtakes in the fields.”
—Ralph Waldo Emerson (1803–1882)
“I find it hard to believe that the machine would go into the creative artist’s hand even were that magic hand in true place. It has been too far exploited by industrialism and science at expense to art and true religion.”
—Frank Lloyd Wright (1869–1959)
