Amadou,
You need to add the clear option:
local country "Benin Togo France"
foreach i of local country {
use `i'.dta, clear
di "I use `i'"
g id = _n
codebook id
}

Objet : Re: st: Re: Problem with foreach
Thanks,
I put a "cap drop id" before issuing the generate command.
And I still got the same problem.
Besides, when stata exits the loop, doesn't it automatically
drop the id variable and leaves the dataset unchanged?
Maybe I have no clue on how foreach proceeds exactely.
Best regards.
Amadou.

Please respond to
statalist
It fails because you are trying to -generate- variable -id- 3 times... and
you can only do that once. -drop id- before closing the -foreach- loop if
it needs to be different for each country.
