Hard to say in the absence of further information. Are these unique
identifiers variables? You really need to make up your mind whether you want
to -append- or -merge-... See their respective help files for examples...

Betreff: st: combining datasets

Dear Statalisters,
I have several small datasets (about 700-1000) each, with unique identifiers
each. I would like to join or merge these datasets but keep their individual

identifiers, is there a way that I can do that?
