# CHANGES
#    19 Jul 00  Use /bin/pwd instead of shell built-in.  This
#               will print the real path vs. the path you used
#               to arrive there when symbolic links are
#               traversed.
#
#    13 Apr 01  Quote the parameter when it is used so it can
#               contain white space.

     #
     # DESCRIPTION
     #    This function will return the full name of the
     #    file or directory (the full name begins at the
     #    root directory).  The full name will be written
