Depending on what you need the screen offset for, there are a few other
(simpler) alternatives.  My experiences are with video application that
need overscan in the video out.  Sometimes the image is shifted from what
you see on the RGB display.  This happens when I use the CMI-VI encoder.
And I have to shift the image to compensate.

Mike Berro (of MicroIllusions) has a utility that will shift the entire
Amiga display (all screens) using hot keys.  I believe this is part of
his VTOT (Video Tools On Tap) shareware utility.  This acts like using
Preferences.  I don't know if you can call it from a script, or whether
you must make the adjustment manually.

If you are shifting the image of an IFF or animation, you can use the
latest version of Display (V3.31, a PD animation player from Hash
Enterprises).  The new version will shift the screen offset when you
press the ',' '.' '[' and ']' keys.  Display is available on PeopleLink,
and will be on Genie as soon as I have time to upload it.

Hope this helps.
