MergeSort is an overloaded routine used to implement a comparison-based sort routine for values in List. List can be a TStrings or TFPList instance. No actions are performed in the routine when List has not been assigned (contains Nil).
The StartIndex and EndIndex arguments allow the initial and final entries in a TFPList instance to be specified. When the values are omitted, they default to the first value (position 0) and the last value (Count-1) in List.
OnCompare is the comparison routine used to determine the order for the sorted values. It can be a TListSortCompare or TStringsSortCompare function, depending on the overloaded variant of the called routine.
MergeSort implements the J. von Nuemann divide-and-conquer algorithm, with an insertion sort used for lists with 6 or fewer elements.
