ATC-CCAP - Cobol/CICS Application Programming

Overview

Duration: 5.0 days

CICS Command Level Programming provides an understanding of the CICS system, application environment and typical applications. The structure of CICS pseudo-conversational application programs are discussed and reviewed in detail. The course consists of a series of lectures, discussions and class exercises with hands-on programming sessions.

Objectives

• Write, compile, walk-thru, and execute CICS programs
• Demonstrate the use of major CICS commands
• Develop user screens utilizing Basic Mapping Support (BMS)
• Assemble, test, and debug BMS maps
• Access data in a CICS program from a VSAM file, a DB2 table, a TD queue, a TS queue
• Compile, debug, and execute CICS programs
