VAX-11 FORTRAN Language Summary

This document, the "VAX-11 FORTRAN Language Summary" published by Digital Equipment Corporation in October 1982 (Order No. AV-M763A-TE), serves as a concise quick-reference guide for programmers using VAX-11 FORTRAN. It specifically includes language features that are VAX-11 extensions to the FORTRAN-77 standard.

The summary covers the following key areas:

• VAX-11 FORTRAN Command Formats: Details the commands and their qualifiers used for compiling, linking, and running FORTRAN programs (e.g., FORTRAN, LINK, RUN).
• VAX-11 FORTRAN Statement Summary: Provides a reference for the syntax and parameters of various FORTRAN statements, including arithmetic/logical/character assignments, I/O operations (READ, WRITE, OPEN, CLOSE), program control (DO, IF, GO TO), data declarations (DIMENSION, TYPE), and other directives. It also includes details on FORMAT field descriptors and carriage control characters.
• VAX-11 Symbolic Debugger Command Summary: Lists commands for interacting with the symbolic debugger, enabling actions like setting breakpoints, examining and depositing data, and controlling program execution.
• VAX-11 FORTRAN Generic and Intrinsic Functions: Presents comprehensive tables of built-in functions (e.g., mathematical, trigonometric, hyperbolic, type conversion, bitwise operations, character functions), specifying their generic and specific names, number and type of arguments, and type of result, along with important notes on their usage.
• ASCII Character Set: Provides a complete listing of ASCII characters, their decimal numbers, and meanings.

Overall, the document is designed as a handy resource for VAX-11 FORTRAN syntax, commands, functions, and character encoding.
