The course begins with a review of CICS Command Level Programming. The structure and flow of several working CICS Programs is discussed in detail.
Basic Mapping Support (BMS) screens also reviewed in detail.
A working CICS Applications is modified to add several NEW features. These new features include the use of PF Keys, changing screen field attributes, help facility for a screen and individual fields on the screen, application paging and error handling.
Build a "large" application where several CICS programs and user screens interface together
The course consists of a series of lectures, discussions, class exercises, and with hands-on programming workshop problems.
Mainframe Training Learning Objectives
As a result of the class, the student will be able to -
- Review working CICS programs
- Refine / add use screens using Basic Mapping Support (BMS)
- Access data in a CICS program from a VSAM file, a DB2 table, a TD queue, a TS queue
- Add additional features to CICS programs (help, PF Keys, change field attributes)
- Compile, debug, and execute CICS programs
Mainframe Training Audience
CICS Command Level Programming Workshop is intended for programmers have worked with CICS programs and must develop more involved applications.
Mainframe Training Prerequisites
Six months of experience with CICS Command Level Programming, TSO/ISPF, COBOL programming and JCL is required.
Mainframe Training Course duration
