I am writing a Clipper application that will run on a Novell network
but needs to be tested under DOS and might have to run in production
on DOS in an emergency.  Is there an interrupt or INT21 call that
can tell me what operating system my application is running under
so that I know whether it is safe to make certain NetWare function
calls?

Replies to this newsgroup or e-mail or both, doesn't matter.
Thanks to all in advance.
