Left censoring problem using S+

I am wondering if the current version S+ handles the problem that
lifetimes are subject to left censoring (or truncation) in addition to
the usual right censoring. If yes, how the "status" variable is coded for
the left censoring, lifetime, and right censoring respectively? I have
tried to check the S+ library, but it is not clear to me. Do I miss
something here? Any suggestion is highly appreciated.
