Running NeWS version 1.1.

    Adobe specifies that `currentfile' "returns the file object from
which the PostScript interpreter is currently or was most recently
reading program input" (Red book, pg.  144).  Yet this does not seem
to work for psh or psview.

    Most commonly this seems to be used to read large bitmaps for the
image operator.  In fact, it seems one of the only ways the read
images that are larger than about 65000 bytes, the maximum length of a
string.  There are workarounds, I think, for this particular
application, but it would sure be nice to be able to run normal
postscript programs without hacking the code so much.

    Is this a bug that I should report or is there some reason this
cannot work in NeWS?  In the mean time, does anyone have a nice way to
handle bitmaps that are larger than 65000 bytes?
