keypressed pauses program - how to do that? [message #3067]

Hi all,
basically what I have is a program like this:

FOR loop=0,1000 DO BEGIN
TVSCL, image(loop)
WAIT, 2
ENDFOR

because the images aren't very big it's quite fast.
to make it slower I inserted a 'WAIT, 2' after the TVSCL line.
But that's not what I want to do. It would be much nicer to have something
like a key-controled slide-show, where e.g. <space> toggles pause/slide mode
and e.g <return> (in pause mode) advances the images manually.
I know there's some function for keyboard-stuff in IDL, but I don't know it's
name, and I have no idea how to implement it, that it works the waz I described
above. Maybe somebody wrote something similar an can help me out now.

thanx in advance
