st: Select sample

["Augusto Hoszowski" <ahosz@indec.mecon.gov.ar>]

Hi ,

I need to select one sample stratified. My  file contains the id_strata, the
size of the sample in the strata and size_sample. What is wrong with  the
syntax ?

program define seleccio
   local tamanio size_sample[`1']
   by id_strata: sample `tamanio', count
end
seleccio 1
