ATC-CCAP - Cobol/CICS Application Programming
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
