C   --*** DBIXYZ *** (EXOLIB) Read database coordinates
C   --   Written by Amy Gilkey - revised 10/14/87
C   --
C   --DBIXYZ reads the coordinate array from the database.  An error
C   --message is displayed if the end of file is read.
C   --
C   --Parameters:
C   --   NDB - IN - the database file
C   --   OPTION - IN - ' ' to not store, '*' to store all, else store options:
C   --      'C' to store coordinates
C   --   NDIM - IN - the number of coordinates per node
C   --   NUMNP - IN - the number of nodes
C   --   XN, YN, ZN - OUT - the coordinates (if OPTION)
C   --   * - return statement if end of file or read error
C   --
C   --Database must be positioned at start of coordinates upon entry;
C   --upon exit at end of coordinates.
