File Number 1800-36 Order Number GC26-37,)3-1 Systems Reference Library IBM 1800 Time-Sharing Executive System Concepts and Techniques The purpose of this publication is to describe the facilities provided by the IBM 1800 Time-Sharing Executive (TSX) System, and to explain the basic concepts and techniques underlying their use. It is intended as a reference and guide for customer systems personnel in the implementation of the TSX system. The manual is divided into four sections. The first section serves as an overall introduction to the TSX system. The second and third sections describe the three main executive programs and discuss some of the important design considerations that bear on the use of standard TSX components. The final section provides selections of programming techniques covering a wide spectrum of TSX usage. The general approach taken is to explain each concept as it is encountered, and, where possible, elucidate that concept by means of an example. Numerous sample problems are included to acquaint the programmer with recommended techniques of TSX programming. A detailed TSX Sample System is specially provided as a tutorial on all aspects of TSX design, usage and implementation.
