~This file contains two versions of the index program.
~The first runs faster than the second by attaching to each
~entry in the list to be sorted a key derived from the 
~appropriate PNAME.  The second would probably be as fast
~if suitable privitives were hand coded.  It as a simpler
~structure, and is ammenable to some improvement in format
~in the case where various objects of different types have the
~same name.
