C  Purpose
C  =======
C
C  XERFFT  is an error handler for library FFTPACK version 5.0 routines.
C  It is called by an FFTPACK 5.0 routine if an input parameter has an
C  invalid value.  A message is printed and execution stops.
C
C  Installers may consider modifying the STOP statement in order to
C  call system-specific exception-handling facilities.
C
C  Arguments
C  =========
C
C  SRNAME  (input) CHARACTER*6
C          The name of the routine which called XERFFT.
C
C  INFO    (input) INTEGER
C          When a single  invalid parameter in the parameter list of
C          the calling routine has been detected, INFO is the position
C          of that parameter.  In the case when an illegal combination
C          of LOT, JUMP, N, and INC has been detected, the calling
C          subprogram calls XERFFT with INFO = -1.
