st: access coefficients from another regression

Dear StataList,
my model consist of two equations x1 und x2 which I estimate seperatly using non linear least squares in Stata 12. α and β denote the estimated coefficients, y and z the variables.
First I estimate x1 using:
nl (x1= {α1}*y1+ {α2}*y2 + {α3}*y3)
Then I estimate x2 using:
nl (x2= {β1}*z1+ {β2*z2 + {β3}*z3)
After the estimation I want to calculate a new coefficient γ using the coefficient α1 from the first equation and β1 from the second equation using the nlcom command, for example:
nlcom (γ= α1/β1)
My question is now, how can I access the coefficient α1 from the first equation x1? How would the code for the nlcom command look like?
Thanks a lot in advance.
Christina
