Fortran

Abstract

The FORTRAN language is intended to be capable of expressing any problem of numerical computation. In particular, it deals easily with problems containing large sets of formulae and many variables, and it permits any variable to have up to three independent subscripts. However, for problems in which machine words have a logical rather than a numerical meaning it is less satisfactory, and it may fail entirely to express some such problems. Nevertheless, many logical operations not directly expressable in the FORTRAN language can be obtained by making use of provisions for incorporating library routines.舡 This quotation is taken from 舠The FORTRAN Automatic Coding System for the IBM 704 EDPM,舡 dated October 15, 1956.
