CICS application programming (EN/NL/FR)

In this 3 day ABIS workshop, participants get an overview of the different CICS TS components which are related to the building of applications. Participants will become familiar with the different aspects of working in a CICS environment. Message processing, data management, the use of different communication options and synchronisation are also discussed.  Intended for application programmers with experience in COBOL/PLI.

Remark: Course description in English; Dutch and French versions are available on the ABIS website. Courses are planned in Dutch, English, and French. Consult the ABIS website for alternate course formats.

Main topics:

• CICS coding: How to code CICS 'command level' instructions • their format, syntax and use • program preparation, development and testing
• Controlling terminals: Coding CICS programs to facilitate interactive conversation with terminals • use of Basic Mapping Support
• Error handling: CICS instructions to trap conditions, warnings or exceptions • the use of development tools and trace and debug facilities
• Interprogram communication: LINK, XCTL and RETURN • the use of communication areas, of channels and containers, of temporary storage, of transient data • automatic task initiation
• Data management: CICS instructions to read and change VSAM files • the browse commands • data base access
• Performance aspects
• Recovery: System and application recovery: the commands for commit and rollback • pseudo-conversational programming
• Distributed working • CICS and the internet • CICS and web services

Intended for/Audience: Application programmers who need to develop CICS applications using 'command level' instructions.

Background/Prerequisites: The students should be experienced in COBOL (see COBOL programming - part 1) or PL/I (see PL/I programming: fundamentals course). No knowledge of CICS is required.

Training Method/Didactics: About half of the time is spent on doing exercises on terminal.

Duration: 3 days.
