George maybe something like this: input str10 a b c one 1 2 two 2 3 one 3 4 two 1 2 five 0 0 one 1 1 end qui count local count=r(N) gen same=0 forvalues i=1/`count'{ replace same=1 in `i' if a[`i']==a[_N] } . list +---------------------+ | a b c same | |---------------------| 1. | one 1 2 1 | 2. | two 2 3 0 | 3. | one 3 4 1 | 4. | two 1 2 0 | 5. | five 0 0 0 | |---------------------| 6. | one 1 1 1 | +---------------------+ Hope this helps, Tim On Sat, Apr 24, 2010 at 5:06 PM, George Chioran <george_chioran@yahoo.com> wrote: > Dear Statalisters, > > I want to know how I > could see if the last observation in a variable X (containing strings) is equal > to other observations in the variable.
