    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 facilities.   

    Arguments   
    =========   

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

    INFO    (input) INT   
            The position of the invalid parameter in the parameter list   

            of the calling routine.
