Description

Two DO loops perform the predefined function substring for the system field sy-abcde in an embedded expression of a string template. The first loop calculates the length from the length of the substring plus a fixed value. The second loop sets the length (constantly) as half the length of the full string. This means that this length is ignored if a longer substring is accessed.
