Re: st: Generating labels

[Carlos Valencia <cavalenciah@gmail.com>]

Current data is problematic because the codification of some cities is
repeated as follows: the main city of an state is codified by 1, the
second by 2 and so on. The main city of the state of Antioquia, would
be (Medellín), and is codified with 1 the main city of the state of
Cundinam (Bogota) is codified by 1 also. So, adding any label for any
single number of city would be misleading. So I wonder if there is any
way to label the number of the city, depending on the code of the
state (which is already labeled). I have tried something like (and
didn't work because of invalid syntax)

label define cityname 1 "Medellín" if state Antioquia

YEAR MONTH SEX STATE       CITY CITYNAME
1996   11           0     Antioquia    1          ....
1988   7             1     Cundinam   1          ...
1982   4             1     Bolivar        1          ....

Thanks again

Carlos
