User Exit Reference › USEREDDF User Exit

USEREDDF User Exit

Use USEREDDF, the editing user exit, to provide input and output editing for site-defined EDITDEF field types (USERn) defined through the EDITDEF configuration file record. During initialization, CA VM:Tape loads the TEXT file specified on the EDITDEF record and passes control to the exit. Also during initialization, a call is made to the exit for each of these fields to allow the exit to specify the length of the field to CA VM:Tape. After initialization, calls are made to the user exit to perform any required data conversion of these fields for display and for entry into the TMC.

The exit must be written in assembler and should be reusable each time it is called. You can modify the fields passed to the user exit. For more information, see the Parameters below.
