DECnet-RSX Programmers Reference Manual Oct87

This document is the DECnet-RSX Programmer's Reference Manual, published by Digital Equipment Corporation in October 1987. It serves as a comprehensive guide for programmers developing network applications for DECnet-RSX systems running on RSX-11M, RSX-11S, RSX-11M-PLUS, and Micro/RSX operating systems.

The manual describes the programming facilities and provides detailed reference information for network programming calls in several languages, including MACRO-11, FORTRAN 77, COBOL, and BASIC-PLUS-2.

Key programming functions covered include:

• Intertask Communication: Enabling programs (tasks) running on different network nodes to exchange messages and data.
• Remote File Access: Allowing applications to perform file operations (open, read, write, append, close, purge, delete) on sequential files located on remote nodes.
• Remote Task Control: Providing capabilities to execute, schedule, abort, or cancel installed tasks on remote RSX or IAS DECnet nodes (primarily for FORTRAN programs).
• Direct Line Access (DLX): Offering a direct interface to the data link layer, bypassing higher-level DECnet services, to build high-performance network applications using Ethernet or point-to-point/multipoint lines.
• Local Area Transport (LAT) Programming: Guiding the development of applications that communicate with remote terminal server devices via LAT application terminals on an Ethernet.

The document is intended for users who write network programs for these specific DECnet-RSX and RSX-11 based systems. It also includes various appendices detailing error/completion codes, object types, and other technical reference information.
