[dongta_ndh]

Please help me.

Hope you are asking for the syntax

To call the user exit from a Oracle Forms trigger, use the syntax
<user_exit>('CONCAT <field1>, <field2>, ..., <result_field>');

If you need any more help let me know and I would answer that.

If you have information about the step to write and use user_exit() in developing Oracle Application Form please help me!
Thanks in advance.
