SH20-1047-4 Customer Information Control System (CICS) Application Programmer's Program Product Reference Manual Program Numbers 5736-XX6 (DOS-ENTRY) 5736-XX7 (DOS-STANDARD) 5734-XX7 (OS-STANDARD V2) The IBM Customer Information Control System (CICS) is a transaction-oriented, multiapplication data base/data communication interface between a System/360 or System/ 370 operating system and user-written application programs. Applicable to most online systems, CICS provides many of the facilities necessary for standard terminal applications: message switching, inquiry, data collection, order entry, and conversational data entry. CICS is available in three systems-two for DOS users and one for OS users. Because the two CICS/DOS systems are compatible with each other and with the CICS/OS system, it is possible to start with a small data base/data communi- cation configuration and move up through DOS into OS. This manual provides information of interest to persons defining, designing, and preparing application programs to execute under CICS.
