st: using macrolists in constraints

[Val�rie Orozco <Valerie.Orozco@toulouse.inra.fr>]

Hi,

In order to write some constraints (to be used in a model), I would like 
to use loops and macrolists whereas writing each constraint one after one.
But it seems I am wrong using the following code :

forvalues i = 1/3{
   local all "[dw`i']dlnp1"
   forvalues j = 2/4 {
       local add "+"
       local element "[dw`i']dlnp`j'"
       local all `"`all' `add'"'
       local all `"`all' `element'"'
   }
   di "`all'"
   constraint `i' `all' = 0
}

What I would like is :

constraint 1 [dw1]dlnp1 + [dw1]dlnp2 + [dw1]dlnp3 + [dw1]dlnp4 = 0
constraint 2 [dw2]dlnp1 + [dw2]dlnp2 + [dw2]dlnp3 + [dw2]dlnp4 = 0
constraint 3 [dw3]dlnp1 + [dw3]dlnp2 + [dw3]dlnp3 + [dw3]dlnp4 = 0

Thank you very much for trying to help me.
