Mainframe Training Overview
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.
- Build applications using the following additional CICS features such as - Storage Control, Paging Transactions, Online Printing, CICS System Information, EIB, system storage, DFHCOMMAREA, Changing field attributes, debugging tool such as InterTest or Xpediter
Learning Objectives
As a result of the class, the attendee 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 read/browse 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
- Debug the application program using aq debug tool - CEDF, InterTest, Xpediter
- Program CICS Paging applications
- Program CICS online printing applications
- Build additional features in a CICS program - retrieving CICS Storage Control and System Information / EIB, pass data via TS Queues / DFHCOMMAREA with copy books, screen / field sensitive help, Channels with their Containers
- Describe the design for a Web Enable front-end to access a CICS back-end program
