Field engineering program

The field engineering program (DFHFEP) is a CICS® system service function primarily designed for an IBM® field engineer to use when installing new terminals. When CICS is running, this program (invoked by the CSFE transaction) transmits a set of characters to the requesting terminal. In addition, the program can be used to echo a message; that is, it repeats exactly what is keyed at the terminal.

This program also supports some general debugging functions.
