User Exit Before (Block) 

Use

You use the User Exit Before function to call a user-defined form routine. The form routine is called before the Interface Toolbox starts to process the block, in other words, before the Toolbox processes the structures and fields assigned to a block.

Each user exit must have 16 parameters.

Input Values

Parameters 1 to 15 are available as input values for the user exit.

If you use tables, you can select the following parameters for the table entries:

The first table entry is transferred to the form routine.

The last table entry is transferred to the form routine.

The current table entry (from the table header) is transferred to the form routine.

Return Value

In the form routine, the return value is parameter 16. The return value of a form routine determines how the block is subsequently processed. The return value can have the following values:

The Toolbox does not process the block.

The Toolbox processes the block.

Activities

In the User Exit dialog box, enter the data for the program, for the form routine, and for parameters 1 to 15.
