About the FEPI samples

Each FEPI sample program performs a specific function and is associated with a CICS transaction. A subset of the sample programs is available in each of the supported programming languages.

The programs and their names are given in Table 1.

There are also some sample resource definitions. Sample definitions for front-end and back-end CICS regions are in the RDO groups DFH$0AZ, DFH$0BZ, DFH$0CZ, DFH$0BZ, DFH$0PZ, and DFH$0VZ. A sample definition for a back-end IMS region is in DFH0IZRI. A sample definition of a CICS TD queue, DFH0IZRQ, is in the DFHDCTG RDO group.
