CICS Command Level Programming with BMS

Mainframe Training Overview

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.

Basic Mapping Support (BMS) is used to develop screen layouts (maps). These maps, used in the class programming exercises, are the basis for understanding the CICS terminal interface.

A model program is used to develop class programs. The major CICS commands and features are used in class exercises.

Programming access will be use the CICS Command Level Interference of COBOL.

The course consists of a series of lectures, discussions, class exercises, and with hands-on programming workshop problems.

Mainframe Training Learning Objectives

Upon successful completion of the course, each student will be able to -

  • 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
Mainframe Training Audience

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

Mainframe Training Prerequisites

Six months of experience with TSO/ISPF, COBOL programming and JCL is required.

Mainframe Training Course duration
