I'm not clear exactly what you want but try this

-h candisc-
click on "also see" and then on "discrim lda postestimation"
look for the "predict" option and click on it to see what is available

But we've got 12 potentially discriminating variables & 2 functions, and I'd like to minimize the chances of mistakes by generating the scores calculated by STATA.  If anyone knows how to do this, I'd appreciate your insights.
