Sascha.
Look at the nlsur postestimation help file. It explains that lincom can be used to test linear hypotheses after nlsur.

Subject: st: NLSUR and TEST linear hypotheses for the parameter
Hello,
I have to estimate a system of nonlinear equations. I use NLSUR and it works
well.
Now, I want to test linear hypotheses for the parameter am+ac+al=1.
I know using regress it is possible to test. But it is dont work in NLSUR.
Thank you for the helping.
Best regards
Sascha
* nlsur - Estimation of nonlinear systems of equations
nlsur

tt}*year*year]+{amc}*m*c+{aml}*m*l+{amt}*m*year+{acl}*c*l+{act}*c*year+{alt}
*l*year) (pfexp =
prexp*[yexp/mexp]*[{am}+{amm}*m+{amc}*c+{aml}*l+{amt}*year]/[1+[{TetaT}
/0.55]]), nls
test am+ac+al=1
* regress - Estimation of regress equations
regress y m c l
test m+c+l=1
