Stack Computers [Guest editor´s introduction]

Those of us who have worked with stack computers for several years have found an unending source of amazement –and some consternation–in how few computer professionals there are who seem aware that there is an entirely different approach to computer architecture from the familiar von Neumann model. Sometimes when such phrases as "zero-address machine" have dropped from my lips, and I see that the phrase had about as much meaning for the listeners as "zero-bit word" might have, I have wished that knowledge of stack machines were more widely spread. Fortunately Jack Grimes, the technical editor of Computer, had the same desire and suggested that an issue be devoted to the subject.
