CTS-300 System User's Guide

This document, the CTS-300 System User's Guide (May 1980), serves as a comprehensive reference for users of the CTS-300 operating system on DIGITAL Datasystem 300 equipment. It details the development and execution of DIBOL programs under either single-user (SUD) or time-shared (TSD/XMTSD) environments, as well as providing instructions for system generation (CTSGEN), system utilities, and configuration. The manual includes sections on keyboard commands, file conventions, the DKED editor, the DIBOL compiler (DICOMP), line printer spoolers, the ISAM (ISMUTL) utility, and the SORT/MERGE utility. Additionally, it lists runtime error messages in appendices for troubleshooting.
