I've never programmed for Win95, so my terminology is out of date.  Same idea,
though:  set and forget.

How much do I have to learn about Win95 programming to write a "console app"?   I'd
like to limit the time I spend on this, given that it's a very small audience of
users, so I've got to leverage whatever is out there and I don't want to buy a
compiler for Win95, which is why I favor Java/Javascript solutions.

Yes, it's a Dial Up Networking connection, using PPP.  The SecurID card access is
via a small .exe file that the users run right after they get connected to the modem
pool:  it's a separate process, and also a black box to me. Once authenticated, they
can go to pretty much any server in the network.
