Program lhw.f was borrowed from Larry Wasserman to read the GSC1.0 and 1.1
CD-ROMs.  It is in Sun FORTRAN which means that the record lengths are wrong,
etc., for DEC FORTRAN.  My hack is in dgm.f which (a) uses integers not
characters for the star numbers, uses TYCHO format RA/Dec integers, and
packs the magnitude and code into the fourth integer.
