thank you, Richard and Michael. I am using Stata 8 and it's up to date. The code you provided worked nicely, Richard, and I'll use it in my program. I still haven't figured out why the -cond()- isn't working. I have to read Gould's link that Michael provide.
Thanks again.
Paul

Well, if it is any consolation, it looks to me like you are doing it
exactly right. In fact, I just tried it with some data I made up using
your exact syntax, and gen cholcat = cond(chol,0,1,9) worked fine.
I am using Stata 8; what version do you have? If not 8, maybe the syntax
has changed across time?
Incidentally, this command produces a var coded 0, 1, and missing, if that
helps any:
gen cholcat = cond(chol,0,1) if chol <.
