Pre-Requisites

The student should have a good knowledge of COBOL/TS, PL/I or Assembler language coding techniques and a conceptual understanding of DASD file organizations.

Lessons

Class participants learn how to write on-line applications using the CICS/TS command level interface. The fundamentals of terminal I/O, program control, file processing and program testing/debugging are presented. Programming techniques that maximize CICS/TS performance and efficiency are discussed in detail throughout the class. This course can be taught at the current release of CICS/TS or any previous release based on the client's needs.

Objectives

Upon completion of this course the student should be able to:
Understand the major CICS/TS management functions and their corresponding tables
(PPT, PCT, TCT, FCT, DCT).

• Design and code application programs for the CICS/TS environment using the following
• CICS/TS functions:
• Exception conditions (HANDLE CONDITION, IGNORE CONDITION)
• Program control (LINK, XCTL, LOAD, RELEASE, RETURN)
• Terminal control (SEND, RECEIVE, HANDLE AID)
• File control (READ, REWRITE, WRITE, DELETE, STARTBR,
• EADNEXT,ENDBR, RESETBR)
• Basic mapping support (MAPSETS, MAPS, SEND, RECEIVE,
• ATTRIBUTES, CURSOR POSITIONING)
• Transient data control (READQ TD, WRITEQ TD, DELETEQ TD)
• Temporary storage control (READQ TS, WRITEQ TS, DELETEQ TS)
• Storage control (GETMAIN, FREEMAIN)
• Access to other system information (ADDRESS, ASSIGN)
• Abnormal termination and recovery (HANDLE ABEND, ABEND, DUMP)

Use the CICS/TS diagnostic facility (CEDF) for testing and debugging application
programs.

Audience
This course is designed for application level programmers who are required to code and maintain
programs which utilize the CICS/TS Command Level Interface.
