Hello MathGroup: When I execute the following list of expressions (in Mathematica v.4.2) I expect to get "f'[5]" from the last expression instead of "3". Is it a bug or something else? ---------------------------- f'[5] f'[_] = 2; f'[5] Remove[Derivative] f'[5] f'[_] = 3; f'[5] Remove[Derivative] f'[5] ---------------------------- If Remove[] is replaced by Clear[] the output from the last expression is "f'[5]" as expected. Would it be the reason to always use Clear[] rather than Remove[]? Thank you, Vadym
