TC-FRAP

This document describes TC-FRAP, a tool designed to allow programmers to prepare symbolic programs via an on-line typewriter on the PDP-1 computer. It covers the following key areas:

• Operational Procedures: How to load TC-FRAP, perform symbolic type-in, correct typing errors, and interact with the Main Control loop.
• Main Control Features: Explains functions for type-out of programs, error handling, initiation of FRAP assembler passes, and clearing the table area.
• TYC (Type Control): Detailed debugging capabilities provided by the TYC program, including register examination, memory scanning, and modifying register contents.
• System Usage: Information on keyboard character corrections, memory location usage, and the intended use of TC-FRAP for remote assembly via the DEC Data-Phone.
• Examples: Practical examples demonstrating how to enter symbolic programs and perform corrections.
