Have you tried to -merge- on the string variable and look at the _merge
variable that Stata generates?

Betreff: st: comparing datasets by string variable
Dear Statalisters,
I need to compare two datasets (the first with 4416 obs. and the second with
144000 obs) by a string variable (which after using recast command has now
the same dimension in both datasets). The string variable is something like
"Surname".
What I need to do is to find which observations, identified by this
variable, belong to both datasets.
I am afraid that the cf command is useless in this case, since the two
datasets have different dimension. Am I wrong? How can I approach the
problem?
Thank you very much.
Alessandro Gambini
