Dear Don, 
with Stata 12.1/SE I was not able to reproduce what you reported; actually
everything seems to work out fine here.

Surely people at StataTech Support can give you some answers about what is
going on.

Good luck,

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

HELP.  What is going on.
