Fortran User's Guide

Preface

This guide describes the compile-time environment and command-line options for the two Sun(TM)TM Fortran compilers: f77 (FORTRAN 77 version 5.0) and f90 (Fortran 90 version 2.0). Runtime error messages and new features of the compilers are listed in appendixes.

Discussion of Fortran programming issues on Solaris(TM) operating environments, including input/output, application development, library creating and use, program analysis, porting, optimization, and parallelization can be found in the companion Sun Fortran Programming Guide.


Note -

This guide covers the Sun FORTRAN 77 and Fortran 90 compilers. The text uses "f77/f90" and "Fortran" to indicate information that is common to both compilers.


Who Should Use This Book

This guide is intended for scientists, engineers, and programmers who have a working knowledge of the Fortran language and wish to learn how to use the Sun Fortran compilers effectively. Familiarity with the Solaris(TM) operating environment or UNIX\256© in general is also assumed.
