Introduction

This book describes the SAS/C CICS Command Language Translator and explains how you can develop CICS command-level application programs in C using the SAS/C Command Language Translator, the SAS/C Compiler, and run-time library.

CICS (Customer Information Control System) is a popular database/data communication (DB/DC) control system offered by International Business Machines Corporation. SAS/C application programs can be developed to take advantage of various CICS services that enable online, real-time transaction processing. Banking and reservation systems are examples of such real-time transaction processing environments. Using the SAS/C Translator, you can develop C programs for a wide range of CICS applications for any system requiring this type of processing.

The SAS/C Compiler is a portable implementation of the high-level C programming language. Using C with CICS is possible because the SAS/C Compiler and Library support the CICS run-time environment--the collection of data and routines that provide interaction with CICS.

This documentation is directed toward experienced C programmers who are familiar with CICS concepts. Experience in applications programming for CICS is helpful, but not required.
