Preface

This manual describes the routines in the Fortran 77 4.2 and Fortran 90 1.2 runtime library.

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 the Sun Fortran 77 and Fortran 90 compilers.

Audience

This is a reference manual intended for programmers with a working knowledge of the Fortran language and some understanding of the Solaris^TM system and UNIX commands.

Multi-Platform Release

The Sun Fortran documentation covers the release of the Fortran compilers on a number of operating systems and hardware platforms:

Fortran 77 4.2 is released for:

Solaris 2.x operating system on:

Fortran 90 1.2 is released for:

Solaris 2.x operating system on SPARC architectures only.

The Fortran documentation describes the Sun compilers on all the above operating systems and platforms. Anything unique to one or more platforms is identified as "(SPARC)", "(Intel)", and/or "(PowerPC)".

Conventions in Text

This manual uses the following conventions:.

Code listings and examples appear in boxes:
WRITE( *, * ) 'Hello world'
The plain Courier font shows prompts and coding.
In dialogs, the boldface Courier font shows text you type in:
demo% echo hello

hello

demo%
Italics indicate general arguments or parameters that you replace with the appropriate input. Italics also indicate emphasis.
Examples use demo% to indicate use of the C shell, and demo$ for the Bourne shell.
The small clear triangle shows a blank space where that is significant:
36.001
Nonstandard Fortran 77 features are tagged with a small black diamond ( ). A program that uses a nonstandard feature does not conform to the ANSI X3.9-1978 standard, as described in American National Standard Programming Language FORTRAN, ANSI X3.9-1978, April 1978, American National Standards Institute, Inc., abbreviated as the FORTRAN Standard.
Fortran examples appear in tab format, not fixed columns. See the discussion of source line formats in the Sun Fortran User's Guide for details.
References to online man pages appear with the topic name and section number. For example, a reference to GETENV will appear as getenv(3F), implying that the man command to access this page would be:

WRITE( , ) 'Hello world'

demo% `echo hello` hello demo%

36.001

man -s 3F getenv
