Yngve Massachusetts Institute of Technology Cambridge Massachusetts A notational system for use in writing translation routines and related programs is described. The system is specially designed to be convenient for the linguist so that he can do his own programming. Programs in this notation can be converted into computer programs automatically by the computer. This article presents complete instructions for using the notation and includes some illustrative programs. IT HAS BEEN SAID that the automatic digital computer can do anything with symbols that we can tell it in detail how to do. If we are interested in telling a digital computer to translate texts from one language into another language we are faced with two tasks. We first have to find out in detail how to translate a text from one language to another. Then we have to tell the computer how to do it. This paper is concerned with the second task. We will present here a specially devised language in which the linguist can conveniently tell the computer to do things that he wants it to do. The automatic digital computer has been designed to handle mathematical problems. It is able to carry out complicated routines in terms of a few different kinds of elementary operations such as adding two numbers subtracting a number from another number moving a number from one location to another taking its next instruction from one of two places depending on whether a given number is negative or positive and so on. In order to instruct the computer to carry out complicated routines simple instructions for the elementary operations are combined into a program. The writing of a program to carry out even an apparently t This work was supported in part by the U. S. Army Signal Corps the U. S.
