Two radio buttons on the same line

I was trying to incorporate radio buttons in my program selection screen..
The radio buttons were comin in 2 different lines..but i wanted them on the same line..
So here is my code to do it..

.....................................................
.....................................................

SELECTION-SCREEN: BEGIN OF BLOCK B1 WITH FRAME TITLE TEXT-001.
SELECT-OPTIONS: PLANT FOR WERKS OBLIGATORY,
COMPANY FOR BUKRS NO INTERVALS,
SO_CDAT FOR ERDAT OBLIGATORY,
PO_TYPE FOR BSART OBLIGATORY.
SELECTION-SCREEN:SKIP.
SELECTION-SCREEN:BEGIN OF BLOCK B2 WITH FRAME TITLE TEXT-002.
SELECTION-SCREEN: BEGIN OF LINE.
PARAMETERS:CLAIMED RADIOBUTTON GROUP GRP1 USER-COMMAND FCODE1.
SELECTION-SCREEN COMMENT (25) TEXT2.
SELECTION-SCREEN POSITION 30.
PARAMETERS: DISP_ALL RADIOBUTTON GROUP GRP1 DEFAULT 'X' .
SELECTION-SCREEN COMMENT (20) TEXT3.
SELECTION-SCREEN: END OF LINE.
SELECTION-SCREEN:END OF BLOCK B2.
SELECTION-SCREEN: END OF BLOCK B1.

INITIALIZATION.
TEXT2 = 'Claim not equal to zero'.
TEXT3 = 'Display all'.

START-OF-SELECTION.
