Programs

A FEPI application consists of a number of programs.

These programs are as follows :

Access
Begin-session handler
Unsolicited-data handler
End-session handler.

Access program
The main purpose of an access program is to start a conversation, communicate with the back-end application, and end the conversation.
Begin-session handler
The begin-session handler transaction is started by FEPI when a connection is acquired. This transaction handles any functions that are required to initialize the session.
Unsolicited-data handler
The unsolicited-data handler transaction is started by FEPI if inbound data arrives on a connection for which there is no current conversation.
End-session handler
The end-session handler transaction is started by FEPI when a conversation ends or a session is to be unbound.
