Dear statalisters,

I have 60 countries in my dataset. "cntrystr" is string variable. To change 
it into a numeric variable, I used the following code:

encode cntrystr, gen(cntry)
label list cntry

It lists 60 countries. Then, I dropped 10 countries and wanted to generate a 
new label list by the following code:

drop cntry
encode cntrystr, gen(cntry)

However, Stata gives the same 60 countries. This is a problem because I want 
to use "forvalues i=1/50 {... }" for my analysis and it is interrupted due 
to missing country numbers. How can I remove dropped countries in 'encode"?

Thank you in advance.
Mike.
