Hi,
Below is the html/javascript that I was hoping would turn the "Abort" button
into a hot abort key. As it wasn't necessary for this example I've just
removed the button altogether but I will come back to the issue of
stop/cancel/abort processing in the next example. I think this "Frames"
idea's got legs so please let me know if you have any knowledge in this area
that may help.
Cheers Richard Maher.
PS. If you've got a chance to look, I couldn't make the Courier Font in the
..green_screen style smaller. Can anyone show me how with this example?
PPS. What controls if a button is Up or Down? I couldn't find the property
or method but sometimes the "send" button stayed down. (I think if disabled
when an alert fired?) Any Ideas how to control that?

<p>
This is an example of a browser-based, html and JavaScript,
client interacting with a VMS hosted Tier3 Application Server
in a connection-oriented and context-rich environment.<br /><br />
You would have noticed that, when this page was initially displayed,
you were immediately prompted for your VMS Username and Password.
Once authorization is successful your credentials, and an accompanying
Persona, are automatically made available to your 3GL User Action
Routines each time their Server Process is chosen to perform work on
behalf of the client. In this example, the user only gets to see those
Print and Batch jobs that they have privileges to view. You can find
the corresponding server code for this example (demo_uars.cob) in your
t3$examples directory.<br /><br />
The session and server connection are terminated when you change
web pages or refresh this page.
