Preface

This manual provides a reference to the Fortran 77 language accepted by the Sun FORTRAN 4.2 compiler f77.

Conventions in Text

This manual uses the following conventions:

Code listing 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 the csh shell and demo% as the system prompt, or the sh shell and demo$ as the prompt.
The small clear triangle shows a blank space where that is significant:
36.001
Nonstandard 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 Fortran User's Guide for details.
The FORTRAN 77 standard uses the convention of spelling the name "FORTRAN" capitalized. Sun documentation uses both FORTRAN and Fortran indiscriminately. The current convention is to use lower case: "Fortran 90".
