st: grouping cases

["Yang, Chongmin" <chongminyang@gmail.com>]

Dear statalist.

I want to choose oecd members from all countries and make dummy variables.
So I wrote like this way:

gen oecd=1 if country=="Australia" | country=="Austria" |
country=="Belgium" | country=="Canada" | country=="Chile" |
country=="Czech Republic" | country=="Denmark" | country=="Estonia" |
country=="Finland" | country=="France" | country=="Germany" |
country=="Greece" | country=="Hungary" | country=="Iceland" |
country=="Ireland" | country=="Israel" | country=="Italy" |
country=="Japan" | country=="Korea, Republic of" |
country=="Luxembourg" | country=="Mexico" | country=="Netherlands" |
country=="New Zealand" | country=="Norway" | country=="Poland" |
country=="Portugal" | country=="Slovakia" | country=="Slovenia" |
country=="Spain" | country=="Sweden" | country=="Switzerland" |
country=="Turkey" | country==" United Kingdom" | country=="United
States"
replace oecd=2 if oecd==.

Is there more efficient way than mine? I think it's very tough to make
variables.

Thanks.
