' SelectionSort.  Short, simple and sloooow.  This is another O(N^2) sort that ' should never be used on long lists.  Like InsertionSort,'  it needs no extra memory (in place) and preserves the existing order of ' records with equal keys.  Unfortunately, it's slower,'  and there's no reason to use it instead of InsertionSort.  Works by looking ' thru the list for the smallest key and placing it first,'  then looking for the next largest, and so on.  If the slow linear search for ' each key is replaced by a faster "priority queue" approach,'  a reasonably fast algorithm can be created (see HeapSort).  Two versions are ' given.  pSelSortS is an indirect (pointerized) version for strings,'  which can be adapted to doubles by changing the declaration of A().  ' SelSortL is a direct version for longs, which can be adapted to integers.'  ' Speed:  Don't ask.'' Bottom line:  Included because it's a clear and simple approach,'  but too slow to be useful.'
