As Philippe suggested, there is more than one way to do Lorenz curves.
As far as I can recall, -glcurve- tends to drop zero obserations
(Philippe is the author, he should know better :)). To circumvent
this, you can do something like
gen alteduc = educ
replace alteduc = c(epsfloat) if alteduc == 0
glcurve alteduc
or whatever is the way you deal with your variables.
