Copy and paste ABAP code example for CHANGE_POINTERS_READ Function Module

The ABAP code below is a full code listing to execute function module POPUP_TO_CONFIRM including all data declarations. The code uses the original data declarations rather than the latest in-line data DECLARATION SYNTAX but I have included an ABAP code snippet at the end to show how declarations would look using the newer method of declaring data variables on the fly. This will allow you to compare and fully understand the new inline method. Please note some of the newer syntax such as the @DATA is not available until a later 4.70 service pack (SP8), which i why i have stuck to the origianl for this example.
