Use the window command to create a new window on the screen. You'll
also want to look at the wset, wdelete and wshow commands in order to
work with multiple windows at one time.
Each window has an ID associated with it. When you create a new window,
get the ID of the window and then you can jump back and forth between
which window you're plotting to. Even though commands like plot will
create a window for you, it's easier to track this if you explicitly
create the window yourself.
; Create two windows
window, 0
window, 1
; Draw something to the first window and then the second
wset, 0
plot, findgen(11)
wset, 1
plot, findgen(11)

Yeah, well, the number of Linux users is steadily increasing and I think
it's fair to say the tone is deteriorating at the same time. When the
proportion of Linux users reaches 90%, I predict this group will be just
as bad as the Madrake Linux one and I won't bother with it any more,
except to make occasional "Windows rules" comments to stir up the angry
hordes.

Read about WINDOW and WSET.

I'll bet they don't talk about tennis on that other group!

I think you are looking for the WINDOW command:
IDL> Window, 1
gives you a window with graphics window index 1, etc.
To make a window the current graphics window (so you
can draw in it), you do a WSET to the proper window
index number. So, to draw in Window 0 again:
IDL> WSET, 0
To draw into window 1,
IDL> WSET, 1
etc.
The current graphics window is always set in !D.Window:
IDL> Print, !D.Window
1
Cheers,
David
P.S. There are books you can read to answer the most
obvious questions. :-)

Ah, let it go and head over to the pub for a beer.
It won't be the last time you get to waste a couple of
hours if you work like me. :-)
Cheers,
David
P.S. I did think it was a heroic effort! And how would
you have ever discovered PNT_LINE on your own?
