Specifications
This publication describes and illustrates the use of the IBM
1800 Time-Sharing Executive System. The calling sequences
to all the programs are described in terms of the FORTRAN
CALL statements. The Assembler language equivalents of
the calling sequences are included in an appendix.
It is assumed the reader has knowledge of the 1800 Data
Acquisition and Control System and the 1800 FORTRAN
Language.
The 1800 Time-Sharing Executive System provides the user

PREFACE
This publication presents the specifications for the MACHINE REQUIREMENTS
IBM 1800 Time-Sharing Executive (TSX) System.
The 1800 TSX system provides a means for genera- The machine units required for operation of the 1800
ting, organizing, testing, and executing programs TSX System are listed below. Normally, only one
for process control and data acquisition applications device per data channel is permitted. For exceptions
and nonprocess operations. to this rule see Test Function under BASIC CALLING
The publication is divided into four parts: SEQUENCE in the Subroutine Library section.
