Calling a Screen as a Modal Dialog

Question

Hi
I have created a 'Z' Transaction which has only one Screen which is of type 'Modal Dialog'. Whenever i run the Z Transaction, i get the screen in a full window size. Is there any way by which i can restrict this screen to a Modal Dialog. I know that we can use call Screen XX Starting at .. Ending at.. Option. But this will help me only when i have two screens.
Can anyone answer this as it is urgent !!!
Rgrds,

Here is an example of what I'm talking about.  Here we have a small program with a selection screen.  When you hit enter, it will call the function module which has the CALL SCREEN...Starting...Ending statement.  This will thru the dialog box in front of the selection-screen.  I believe that this is the functionality that you required.
The program code......
report zrich_0003.
data:  br_itab type table of zbrbin with header line.
parameters: p_check.
at selection-screen.
  call function 'Z_BIN_LOC'
       tables
            br_itab = br_itab.
The function module....
FUNCTION Z_BIN_LOC.
*"*"Local interface:
*"  TABLES
*"      BR_ITAB STRUCTURE  ZBRBIN
  CLEAR: ITAB. REFRESH: ITAB.
  CLEAR: OK_CODE, SAVE_OK.
*Loop thru parameter table and fill up screen.
  LOOP AT BR_ITAB.
* Entry already exists........get bin location.
    SELECT SINGLE * FROM ZBRBIN
         WHERE VBELN = BR_ITAB-VBELN.
    IF SY-SUBRC <> 0.
      CLEAR ZBRBIN-BIN.
    ENDIF.
    ITAB-KDAUF = BR_ITAB-VBELN.
    ITAB-BIN = ZBRBIN-BIN.
    APPEND ITAB.
  ENDLOOP.
  REFRESH CONTROL 'ITABCON' FROM SCREEN '0100'.
* call entry screen.
  CALL SCREEN 100 STARTING AT 10 5
                  ENDING AT 85 16.
ENDFUNCTION.
