st: Creating a variable which collects info on other members

[Vincenzo Carrieri <vincenzo.carrieri@gmail.com>]

Dear Statalisters,

I need to create a variable which collects the information on another
household member.
In particular, I have a variable weight (var name) for each individual
and a dummy variable  which is equal to one if the person is married
with the head of household (the head of household is identified by a
dummy variable relpar (var name) which is equals to one when the
person is head of houseold).

I need to create a variable that for each head of household collects
the weight of his wife  (or husband).
How can I do this on stata?

Any help is appreciated,

Vincenzo
