Does anyone know why the response to the attempted use of a function with an unknown option differs depending on whether the function is built in or user-defined? If I try to use, say, Plot, with an unknown option (call it "newopt"), I get the error message Plot::optx: Unknown option newopt in Plot[.....]. However, if I use a user-defined function with an unknown option, I get no error message -- rather, the option is simply ignored. Bob Lawrence
