Gregory writes about Client Server.

I would advise sockets. If you are writing in Cobol and Image, read and
write to a socket.
At least that way you'll be in command on what you do with what you
receive.

If you allow outsiders to establish a session, well they could do
anything - if they found out how to be manager.sys.

I would also not attach the HP3000 to the internet directly unless
through firewall/routers etc.

Mail me privately for Cobol to socket stuff. Look at our web site
http://www.bankmed.co.za for an example of how it works.

Regards

Neil
