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
