ALTAC, FORTRAN, and compatibility
Saul Rosen · 1961
One of the major aims in the development of universal or common problem-oriented languages has been to permit a user to make the transition from one computer to another without the necessity of a complete reprogramming job. The ALTAC compiler, compatible with FORTRAN II, has been used to implement such a transition from the IBM 704 to the PHILCO 2000 at a number of installations. To the best of my knowledge this is the first time that a compiler has assumed the major burden of transition from a large scale computer of one manufacturer to an even larger scale computer of another manufacturer.
