Problem in report using submit

Question

Hi ,
   I created a report by submitting standard program RM06EF00 with the selection parameters and exported the list to ABAP Memory. I read the ABAP Memory list in the calling program using LIST_FROM_MEMORY and converted it into asci using LIST_TO_ASCI. I got the data in an internal table ( IT_ASCI). my requirement is to add a check box per PO number and need to display it using classical repot. When i select the checkbox, corresponding PO number need to be selected and sent for processing. Also I need to add SELECTALL and DESELECTALL buttons in the menu which will enable the selection of checkboxes accordingly.
I am a fresher and not aware of much of ABAP. can please anybody guide me how to proceed.
