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 Ade "Michael Blasnik" <michael.blasnik@verizon. net> To: statalist@hsphsun2.harvard.edu Sent by: owner-statalist@hsphsun2. cc: harvard.edu Subject: st: Re: multiple )))brackets, is there a more efficient way? 25-May-2004 14:45 Please respond to statalist@hsphsun2.harvar d.edu 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.
