I still don't have 1.1, but in 1.0, currentfile does indeed work.
It cannot work with the distributed psview, however, because psview
wraps your input inside of an enveloping PostScript program.
With a bit of work, you can modify psview to read the file directly.
This has the added advantage that you can do semi-interactive
PostScript hacking: just modify the input file and invoke redraw.
(You might also do something ugly like change the close gizmo into a
redraw gizmo.)

For extra credit, modify psview to maintain an 8.5 X 11 aspect ratio
when resized.
