RE: st: intcens: how to estimate mean and variance after intcens

Dear Stata users,
I wish to create dummy variables containing missing (.), and thus used
formula COND(IF, THEN, ELSE) but missing (.) no longer existed. An example
as follows:
I need to generate (wcgrp) from waist circumference (wc) as 1, 0 or missing
(.), then typed:
generate wcgrp = cond(wc>90&wc!=.&sex==1|wc>80&wc!=.&sex==2, 1, 0)
but (wcgrp) had only 1 and 0, and missing was regarded as 0. Then, I tried
generate wcgrp = cond(wc>90&wc!=.sex==1|wc>80"wc!=.&sex==2, 1, 0, .), but
nothing changed.
Are my commands correct? Anyone knows the solution, please give your help.
Thank you
