hI,

You can also check the transaction ABAPDOCU which gives you lot of sample programs.

Go to SE38 and give demodynpro and press F4.

You will get a list of demo module pool programs.

For examples:

DEMO_DYNPRO_TABLE_CONTROL_1 Table Control with LOOP Statement

DEMO_DYNPRO_TABLE_CONTROL_2 Table Control with LOOP AT ITAB

Thanks Ashish and Ferry!

I really appreciate it...

hi mark,

There are lot of DEMO programs on Dialog Programming in SAP.

<b>

1) Goto ABAPDOCU Tcode.

2) Under ABAP DOucmentation and Examples, Select ABAP USER DIAlLOGS....

3) Then Select SCREENS.

4) Under this select Processing Screens for Simple Dialog Programs.</b>

One such simple program...........

PROGRAM demo_dynpro_input_output .

DATA: input TYPE i,

output TYPE i,

radio1(1) TYPE c, radio2(1) TYPE c, radio3(1) TYPE c,

box1(1) TYPE c, box2(1) TYPE c, box3(1) TYPE c, exit(1) TYPE c.

CALL SCREEN 100.

MODULE init_screen_100 OUTPUT.

CLEAR input.

radio1 = 'X'.

CLEAR: radio2, radio3.

ENDMODULE.

MODULE user_command_0100 INPUT.

output = input.

box1 = radio1.

box2 = radio2.

box3 = radio3.

IF exit NE space.

LEAVE PROGRAM.

ENDIF.

ENDMODULE.

Reward me if useful...........
