An easy-to-use handbook for experienced programmers and scientists, this highly readable survey offers a concise but thorough description of the whole of Fortran 77, including practical advice on program portability, design, testing and documentation. The book benefits from the author's long association with the Fortran standardization committee (X3J3), and his extensive experience with large-scale processing in high-energy physics. Since Fortran 77 is the only practical choice for sizable scientific numerical and engineering applications, this will be an invaluable handbook for computer scientists working with engineers and physicists engaged in large-scale computation.
