This manual is a reference guide for TCDMS system programmers and data base administrators at TCDMS installations . It contains a description of the TCDMS functions which define a data base and which create a data base control block (DBCB). It is written with the assumption that its readers have a working knowledge of data base design. For this reason, it offers no instruction in general data base concepts. The user of this manual should have designed the structure of his installation's data base. The information in this manual enables him to create the TCDMS system files which both identify this structure to TCDMS and allow the application programmers at the installation to access the data within the structure.

This report is part of the collection of scanned historical documents available to the public.
