Hi Paul,

An ERROR may have any arguments, but if the first argument is a
STRING(error message). Therefore, the signature should be sq
(string+uint16).
In my opinion the error message string is not relevant, the client
applications
can use it or not. If we consider internationalization, this string will not
the useful.

Regards,
Claudio.
