   14: *  =======
   15: *
   16: *  XERBLA  is an error handler for the LAPACK routines.

   18: *  invalid value.  A message is printed and execution stops.
   19: *
   20: *  Installers may consider modifying the STOP statement in order to
   21: *  call system-specific exception-handling facilities.
