The following lines should do the job

. logit y x
. predict phat, p
. g correct = (phat > 0.5) == y
. ta correct

By the way, if you are keen on logit (and related) models, you may find the -spost- package useful

. net from http://www.indiana.edu/~jslsoc/stata/
. net install spostado

Is there an easy way to determine the percentage of correct
classification (predicted probabilities) after a logit (or logistic)
regression (equivalent to Predicted/Percentage correct in SPSS)?
