TOPS-10/TOPS-20 COBOL Conversion Utility Guide

This document provides instructions for using the 68274 utility, which automates the conversion of COBOL-68 source code to COBOL-74 on DEC's TOPS-10 and TOPS-20 systems. It covers building the converter, processing files, handling COPY library statements, and managing reserved words. Detailed information is provided on specific conversion rules for the four COBOL divisions (Identification, Environment, Data, and Procedure), along with guidance for interpreting diagnostic messages generated during the conversion. Appendix A highlights the specific technical differences between the COBOL-68 and COBOL-74 standards.
