Developing CICS compatibility interfaces

There are a number of ways that you can customize the dynamic allocation sample application program, used to allocate or deallocate data sets dynamically.

Overview of the dynamic allocation program
The dynamic allocation (DYNALLOC) sample application program makes available to the CICS terminal operator most of the functions of DYNALLOC (SVC 99).
Installing the program and transaction definitions
Transaction and program definitions for the dynamic allocation sample program are provided in the sample utilities resource definition group DFH$UTIL.
The dynamic allocation program: terminal operation
When transaction ADYN is entered at a terminal, the operator is presented with a formatted display. The top part of the display is for entering commands, the bottom part for receiving messages from the program.
Using the dynamic allocation program's Help feature
The program includes a limited “help” feature, driven by the program's keyword table.

The flow of control when a DYNALLOC request is issued
When a DYNALLOC request is issued, the main program, DFH99M, calls a series of subsidiary programs to process the request.
