Appending 2 internal tables

Instead of using the normal loop-endloop approach for this kind of programming, use the variation of the append command. Care should be taken that the definition of both the internal tables should be identical. 

Not Recommended

            Loop at int_fligh1.

             Append int_fligh1 to int_fligh2.

            Endloop.

Recommended

            Append lines of int_fligh1 to int_fligh2.
