Basically, it allows you to view another users screen. It brings up a list
of users who are signed on and you select the job you want. It then displays
their screen exactly as they see it.

It uses a message queue break handling program and data queues to do this.
When the user signs on, his job creates a message queue in QRPLOBJ. The
message queue name incorporates the job number so it is always unique and
can be easily determined. The message queue is set in break mode with the
break handling program set to the screen scraper program.

When you request to view the screen, a message is sent to that message
queue. The break handling/screen scraper program is fired off which gets the
current screen and sends it back to your job in a data queue, where it is
displayed. The user is not aware this is happening.

To get a list of users who are signed on. I simply get a list of message
queues in QRPLOBJ.

In the version that I use, I have added additional functions to the break
handling program so that I can, for example, dump the contents of the QTEMP
library, or sign off the job. Once the break handling program takes control,
the sky's the limit.
