ATC-CCAP - Cobol/CICS Application Programming

Overview

Duration: 5 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

Audience

CICS Command Level Programming is intended for programmers who must understand the flow of CICS and write and debug CICS COBOL application programs.
