FEPI

The Front End Programming Interface (FEPI) is an integral part of CICS®. You can use FEPI to write CICS applications that simulate terminals to access other CICS or IMS programs. The FEPI system initialization parameter specifies whether or not you want to use the Front End Programming Interface feature.

Defining FEPI

You can define the FEPI system initialization parameter in the following ways:
  • On the PARM parameter of the EXEC PGM=DFHSIP statement
  • In the SYSIN data set of the CICS start up job stream
  • Through the system console
  • In the DFHSIT macro

Values for FEPI

FEPI={NO|YES}
Valid values for the FEPI system initialization parameter are as follows:
NO
NO is the default value for FEPI. FEPI support is not required. You should specify NO on this system initialization parameter (or allow it to default) if you do not have the feature installed, or if you do not require FEPI support.
YES
You require FEPI support, and CICS is to start the CSZI transaction.

For information about what is required to run FEPI, see FEPI analysis and planning.
