OR just use a recode or is this missing the point?

gen origin = natio
recode origin 3=7 8 12 69 139 141=10 14=8 ... etc

cheers

The suggestion to use inlist may be a step in the right direction, but if
you have a coding for every county in the world  or any list with more than
a few dozen codings, I would think that you should create a dataset with
the
codings (often this coding information is available in a way that makes the
dataset creation fairly straightforward) and then use -merge- to bring them
in.

sort nation
merge nation using nationcodes

You can always list the nationcode file to document what the mapping is.
