To better guide you, please can you describe your goals--
are you trying to set-up an emulation environment, or are
you trying to implement a few transactions where the user
sees a page you've created, enters a request and the answer
comes from your mainframe screen applications?
If the latter, how many transactions and how many host
screens are involved?
Have you been reading the Tutorial, or have you been looking
at the documentation only?
Sorry for the confusion--Screensurfer is a very flexible
product which is used for many different purposes, so it is
hard to focus the documentation on a single one of those...
