Segment UOP1, the first of 2 user exits, is called before segment CVIQ builds its internal routing table and enters segment CVI1 to duplicate the message.
Segment UOP1 allows the routing destination of the message to be modified. If desired, the message can be suppressed by turning on the Message Suppression Indicator (EBX074). The message can also be rerouted by changing the routing code that has been passed to the user exit in Register 6 (R6). The message can be routed to a functional support console (FSC) on your TPF system or on another TPF system.
To reformat a message, alter the text of the message that is in the message block on data level 6. If the message is changed in this exit, all recipients get the changed version. To change the message format for just one FSC destination, place the corresponding routing code in the User Format Indicator (EBX072-EBX073). When the User Format Indicator has been set, UOP2 is entered to enable you to reformat the message for the intended receiver.
The output of the exit is used to build the routing table, and to show whether to invoke the second exit, UOP2.
