PURPOSE

       XERBLA   is  an error handler for the LAPACK routines.  It
       is called by an LAPACK routine if an input  parameter  has
       an  invalid  value.   A  message  is printed and execution
       stops.

       Installers may consider modifying the  STOP  statement  in
       order  to  call system-specific exception-handling facili­
       ties.

       SRNAME  (input) CHARACTER*6
               The name of the routine which called XERBLA.

       INFO    (input) INTEGER
               The position  of  the  invalid  parameter  in  the
               parameter list of the calling routine.

               End of XERBLA
