TOPS-20 FORTRAN Installation V10 May85

This document, the "TOPS-20 FORTRAN Installation Guide (AA-P344B-TM, May 1985)", provides comprehensive instructions for installing FORTRAN-20 Version 10 software on TOPS-20 V4.1 or V5.1 operating systems.

The manual covers the installation of the FORTRAN compiler, FOROTS (object-time system), FORLIB (library), and FORDDT (debugger). Key aspects include:

1. Standard Installation: Detailed steps for installing the ready-to-use FORTRAN components from a 1600 BPI distribution tape using the DUMPER utility, creating necessary directories, and copying files to the system area (SYS:). It notes that the distribution tape might also include LINK Version 6.0 and DDT Version 43, with instructions for handling both scenarios.
2. Testing: Procedures for verifying the FORTRAN installation using a standalone test module or the UETP (User Extensible Test Package).
3. Building from Sources (Nonstandard FORTRAN): For users desiring to modify the standard FORTRAN compiler, FOROTS, FORLIB, or FORDDT, the guide outlines the process of building these components from their source files. This involves specific versions of tools like BLIS10, LINK, and MACRO, and using control files (e.g., B20FTN.CTL, B20FRS.CTL). It emphasizes that building from sources is a computationally intensive task.
4. Patching: Instructions for applying source code patches to the FORTRAN product, detailing the format and methodology for incorporating changes.
5. Integration: Specific procedures for building and integrating DBMS Version 6.1 with FORTRAN-20, and guidance on using SORT Version 5 with FORTRAN-20.

The installation requires operator or WHEEL privileges and involves creating various directories for documentation, system files, source code, and test files.
