  Arguments don't match (ERR=88)

  The arguments in a function call do not match  the  arguments  defined
  for  the  function, either in number or in type.  Change the arguments
  in the function call to match those in the DEF or change the arguments
  in the DEF.  This error cannot be trapped with a BASIC error handler.
