Also, }has the format of this data area been released? Yes, there is a portable way of accessing it. No, the format has not officially been released. However, it is described in INTER290.ZIP. Yeah, but you have to be very careful about *what* you mount *where*. Basically, DOS gets very upset if you try to join a network drive, or if you try to join something anywhere but root, or if the directory you're joining it to doesn't exist, ad nauseum. JOIN does an awful lot of checking before it tells you "bad parameter". Real *good* error message, that. -- --russ (nelson@clutx [.bitnet | .clarkson.edu]) Russ.Nelson@$315.268.6667 Violence never solves problems, it just changes them into more subtle problems
