VAX FORTRAN Language Summary

This document is the "VAX FORTRAN Language Summary," published by Digital Equipment Corporation (DEC) in September 1984 (a revision of the October 1982 first printing).

It is intended as a quick reference for programmers writing FORTRAN programs, rather than a formal or complete language description. The document specifically highlights VAX extensions to the FORTRAN-77 standard using blue text.

Key contents include:

• Command Formats: Details for the FORTRAN compiler, LINK command (for creating executable images), and LIBRARY command (for managing text and object module libraries).
• Language Summary: An overview of the required order and syntax of various FORTRAN statements, and a list of VAX FORTRAN expression operators with their precedence.
• VAX Symbolic Debugger Command Summary: A comprehensive list of commands and their qualifiers for debugging FORTRAN programs.
• VAX FORTRAN Generic and Intrinsic Functions: Extensive tables detailing available functions, their arguments, and return types, including notes on their usage and specific behaviors.
• VAX FORTRAN Run-Time Error Summary: A list of common run-time error codes, their severity, and corresponding message texts.
• Character Sets: Definitions for the Standard FORTRAN 77, VAX FORTRAN, and ASCII character sets.

The document also provides contact information for ordering additional Digital Equipment Corporation documentation.
