I rather like -encode- for this sort of job

. lab def barnumber 1 "A" 2 "B", modify
. encode country , gen(barnumber) label(barnumber)

Notes
* I always put -modify- after label definitions to make sure that a do file
won't run into an already defined label (usually the result of running the
do file a moment earlier)
* -encode-'s option -label- will use the label mappings you have already
defined. Any other string values will be added to the defined value label.
* there is an additional option -noextend- which prevents -encode- from
running if it encounters values that are not in the label you specified.
Handy if you have dodgy things in your data that you are unaware of.
