Anat,
There's not much I can say except that it works for me with Stata
12.1. Maybe you want to copy your exact input/output as it appears in
your results window?
. do "/tmp/SD05932.000000"
. sysuse auto,clear
(1978 Automobile Data)
. keep in 1/5
(69 observations deleted)
. rename make dmu
.
. dea length weight = mpg, saving(deaout)
