problem in call transaction using FD33 t code

Hi all i'm developing a report in that in that i'm calling a tcode FD33.

I want to skip the initial screen.For that i need to pass Customer , Credit control area and status from my program to that tcode.

But my problem is that how to pass the value to check box.

i.m writing the following code

   "Set parameter ID for transaction screen field

        SET PARAMETER ID 'KUN' FIELD W_ALV-KUNNR.

        SET PARAMETER ID 'KKB' FIELD W_ALV-VKORG.

•        "Execute transaction FD33, and skip initial data entry screen

        CALL TRANSACTION 'FD33' AND SKIP FIRST SCREEN.

So how to set the value of the STATUS check box.

thanks in advanced.
