Introduction
This manual provides information on implementing Fortran 77 programs
using IRIX™ and the IRIS®-4D™ series workstation. This implementation
of Fortran 77 contains full American National Standard (ANSI)
Programming Language Institute Fortran (X3.9–1978). Extensions provide
full VMS Fortran compatibility to the extent possible without the VMS
operating system or VAX data representation. This implementation of
Fortran 77 also contains extensions that provide partial compatibility with
programs written in SVS Fortran and Fortran 66.
Fortran 77 is referred to as “Fortran” throughout this manual except where
distinctions between Fortran 77 and Fortran 66 are being specifically
discussed.
Corequisite Publications
Refer to the Fortran 77 Language Reference Manual for a description of the
Fortran language as implemented by the Silicon Graphics® IRIS-4D series
workstation.
Refer to the IRIS-4D Series Compiler Guide for information on the following
topics:
• an overview of the compiler system
• improving program performance by using the profiling and
optimization facilities of the compiler system
• the dump utilities, archiver, and other tools used to maintain Fortran
programs
