Hi Shekhar,
REPORT ZBHMOD1 .
DATA:OKCODE1 LIKE SY-UCOMM,
OKCODE2 LIKE SY-UCOMM.
DATA:N1(10) TYPE N,N2(10) TYPE N,RES(12) TYPE N.
MODULE USER_COMMAND_1000 INPUT.
CASE OKCODE1.
WHEN 'NEXT'.
RES = N1 + N2.
SET SCREEN 1001.
WHEN 'CLEA'.
CLEAR:N1,N2.
WHEN 'BACK'.
SET SCREEN '0'.
ENDCASE.
ENDMODULE. " USER_COMMAND_1000 INPUT
MODULE STATUS_1000 OUTPUT.
SET PF-STATUS 'xxxxxxxx'.
SET TITLEBAR 'TIT1'.
ENDMODULE. " STATUS_1000 OUTPUT
MODULE USER_COMMAND_1001 INPUT.
CASE OKCODE2.
WHEN 'BACK'.
SET SCREEN 1000.
ENDCASE.
ENDMODULE. " USER_COMMAND_1001 INPUT
MODULE STATUS_1001 OUTPUT.
SET PF-STATUS 'xxxxxxxx'.
SET TITLEBAR 'TIT2'.
ENDMODULE. " STATUS_1001 OUTPUT

REPORT ZBHMOD2.
DATA: OKCODE1 TYPE SY-UCOMM,

DNAME(10) TYPE C.
MODULE STATUS_1000 OUTPUT.

Every Screen has a pbo and a pai.
Screen elements are the textbox, buttons, radio buttons and check boxes .....
If we want to pass data from a abap program to a screen element, we have to create a variable with the name we have given in the screen.So whatever the value is present in that variable is reflected on to the screen element.
Here is an example :
Using subscreens and some of the screen elements
REPORT demo_dynpro_subscreens.
DATA: ok_code TYPE sy-ucomm,
save_ok TYPE sy-ucomm.
DATA: number1(4) TYPE n VALUE '0110',
number2(4) TYPE n VALUE '0130',
field(10) TYPE c, field1(10) TYPE c, field2(10) TYPE c.
CALL SCREEN 100.
MODULE status_100 OUTPUT.
SET PF-STATUS 'SCREEN_100'.
ENDMODULE.
MODULE fill_0110 OUTPUT.
field = 'Eingabe 1'(001).
ENDMODULE.
MODULE fill_0120 OUTPUT.
field = field1.
ENDMODULE.
MODULE fill_0130 OUTPUT.
field = 'Eingabe 2'(002).
ENDMODULE.
MODULE fill_0140 OUTPUT.
field = field2.
ENDMODULE.
MODULE cancel INPUT.
LEAVE PROGRAM.
ENDMODULE.
MODULE save_ok INPUT.
save_ok = ok_code.
CLEAR ok_code.
ENDMODULE.
MODULE user_command_0110 INPUT.
IF save_ok = 'OK1'.
number1 = '0120'.
field1 = field.
CLEAR field.
ENDIF.
ENDMODULE.
MODULE user_command_0130 INPUT.
IF save_ok = 'OK2'.
number2 = '0140'.
field2 = field.
CLEAR field.
ENDIF.
ENDMODULE.
MODULE user_command_100 INPUT.
CASE save_ok.
WHEN 'SUB1'.
number1 = '0110'.
WHEN 'SUB2'.
number1 = '0120'.
CLEAR field1.
WHEN 'SUB3'.
number2 = '0130'.
WHEN 'SUB4'.
number2 = '0140'.
CLEAR field2.
ENDCASE.
ENDMODULE.
flow logic for screen 100
PROCESS BEFORE OUTPUT.
MODULE STATUS_100.
CALL SUBSCREEN: AREA1 INCLUDING SY-REPID NUMBER1,
AREA2 INCLUDING SY-REPID NUMBER2.
PROCESS AFTER INPUT.
MODULE CANCEL AT EXIT-COMMAND.
MODULE SAVE_OK.
CALL SUBSCREEN: AREA1,
AREA2.
MODULE USER_COMMAND_100.
flow logic for screen 110
PROCESS BEFORE OUTPUT.
MODULE FILL_0110.
PROCESS AFTER INPUT.
MODULE USER_COMMAND_0110.
flow logic for screen 120
PROCESS BEFORE OUTPUT.
MODULE FILL_0120.
PROCESS AFTER INPUT.
flow logic for screen 130
PROCESS BEFORE OUTPUT.
MODULE FILL_0130.
PROCESS AFTER INPUT.
MODULE USER_COMMAND_0130.
flow logic for screen 140
PROCESS BEFORE OUTPUT.
MODULE FILL_0140.
PROCESS AFTER INPUT.
