How to capture values dynamically from output screen

Hi all,

I have a new requirement.

i developed a report which is showing output correctly. Here i have to take a check box for every record in output screen. if i check some of the check boxs then it should allow for further processing.

i succeeded upto put checkboxes on output screen.

but i don't know how to capture the values of checkboxes of every record into an internal table. it is necessary to capture into an internal table

will it be work by using LOOP AT SCREEN statement.

could you please explain with examples. it is normal report program only.

i would appreciate an early reply
