Ending the listener user exit routine

Using the EOT and EOM parameters, you can specify on the ENFREQ macro whether the system should automatically delete the listener user exit routine when the listener's task ends (EOT) or when the address space ends (EOM). If you specify SRBEXIT then you must specify EOM=YES because the exit routine runs in the listener's address space and ends with the listener.

Only certain combinations of EOT and EOM are valid. The following chart shows which combinations are valid.

Table 1. Valid EOT and EOM parameter combinations

EOT	EOM	Exit type
EOT=YES	EOM=YES	EXIT or SRBEXIT
EOT=NO	EOM=YES	EXIT or SRBEXIT
EOT=NO	EOM=NO	EXIT

For example, to end the exit routine when the listener's task ends or the listener’s address space ends, specify EOT=YES and EOM=YES. To end the exit routine when the listener's address space ends, but not when the listener's task ends, specify EOM=YES, EOT=NO.
