Thanks Dave!

Both (level='M') and (level=2) worked. But if I need both of them I have to have two table statements or run proc freq twice. If I try to capture the dataset with ods output statement, I'll get both in the dataset, but no indication which is come from which. I guess I can assume the first second comes from first table statement and second comes from second. I wish this could be easier :-)

For statistician, can I simply minus one CI from 1 to get the other?

Ya

ods output BinomialProp=xx;

proc freq data=sashelp.class; table sex / binomial (level=2); table sex / binomial (level=1); run;;
