Adding a New Winda,v to One of Your
Screens
At any time, you can add any window from
screen 0 to screens 1 through 9. The window
that you add cannot already be on those screens.
To add a new window:
1.
If your work station is not in Control Mode,
press the WSCtrl key.
This line should appear at the bottom of your
screen:
WSCTRL WINDOW=A SCREEN=O
This line shows, for example, that window A
on screen 0 is active.
2. If this is not the screen profile you want, type
the number of the screen to which you want
to add a window.
That screen profile will appear on your
screen. For example, if you typed 2, the line
at the bottom will change to:
WSCTRL WINDOW=B SCREEN=2
