st: Wald test cross-model with 3SLS

["GROSLAMBERT Bertrand" <Bertrand.GROSLAMBERT@cote-azur.cci.fr>]

I would like to use the stata commands "suest" and "test" to test the
equality of coefficients across various systems of equation obtained
with reg3. Apparently it is not possible after reg3 (problem with
predict, scores). Would you know an alternative solution ? Many thanks
in advance.
