This is not the version that was posted a month ago; if anybody is sending
that to the original poster please mail to me also.  This is just the code
to actually do it, one could wrap it in a redefined showpage to do it for
each page in a postscript file.

This code takes an arbitrary string and an arbitrary rectangle.  There is
some strange interaction with the setscreen stuff that makes the orientation
of the screen a little off from the orientation of the text.  If ANYBODY can
suggest a way to fix this I would be quite grateful!

Anyway, you translate to the lower left corner of the rectangle, then push
the coordinates of the upper right corner and the text onto the stack.  Then
you call the "sash" operator.  See the test program at the end.
