st: option noomit not allowed

Dear All
I just tried to run a logistic regression and got the response "option noomit not allowed"
I had done the exact same regression on the same dataset a while back and got some results; today not so.
So I tried it using
sysuse auto.dta
logistic foreign mpg,
where foreign is a 0/1 variable that mpg is continuous.
and I got the response
"option noomit not allowed"
I tried it with xi: as in
xi: logistic foreign i.rep78 and got
. xi: logistic foreign i.rep78
i.rep78 _Irep78_1-5 (naturally coded; _Irep78_1 omitted)
note: _Irep78_2 != 0 predicts failure perfectly
_Irep78_2 dropped and 8 obs not used
option noomit not allowed
r(198);
HELP. What is going on.
Don
