This method returns the value of a number type keyword. No test is performed to determine if the keyword exists. If the return value is 0, we do not know whether the keyword has the value 0 or that it does not exist. To test whether the keyword exists, call KwdExists before this method. Alternatively, KwdGetNumEx returns 2 parameters: a boolean status code and the keyword value.
