Try 

xi: bootstrap _b, eform reps(2000) dots: logistic hc i.agecat i.educ
i.sexpcat currrltn

Polis, Chelsea B.

I am doing a logistic regression (xi: logistic hc i.agecat i.educ
i.sexpcat currrltn).  When I tried to bootstrap the data (bs "xi:
logistic hc i.agecat i.educ i.sexpcat currrltn" _b, reps(2000) dots),
the coefficients are not exponentiated.

I tried typing "eform" after the comma (and tried using both logit and
logistic as the main command) but STATA says "option eform not allowed"
(even though eform does show up in the help file).  I am using STATA/SE
10.1 for Windows, on a computer running Vista, if that matters.  Can
anybody tell me what I am missing here?  I know I could exponentiate
everything by hand, but I can't imagine that people do this each time
they bootstrap.
