                      9: .sh DESCRIPTION
                     10: CLOSER is used to close a relation which was opened by OPENR.
                     11: If the number of tuples in the relation were changed by the program,
                     12: CLOSER will update the RELTUPS field in the relation relation.
                     13: If all relations are opened for reading only,
                     14: (i.e. the number of tuples could not be changed)
                     15: it may be desirable to use INPCLOSER instead of CLOSER.
                     16: CLOSER should always be called once for each OPENR.
