I am using ghostscript with the x11 driver, to preview documents
created with tex and dvips.

I imagine that there must be standard postscript commands, to
display the previous page; to jump ahead a few pages; and to
display page number N.  I'd be most grateful if someone would
email me the command lines for the ghostscript interpreter, that
do these things.

Note:  I know that the "right" way to do this is with ghostview.
I've compiled ghostview (with gcc 2.2.2 -O2), and it works fine --
except that the overhead for the ghostview "shell" is too much for
my small machine (386/25MHz, 8 Meg RAM, Sunsoft/ISC 3.0 Unix).  So,
the way to go, in my case, is with the slightly less convenient
"raw" ghostscript interpreter (which works fine).

Please email, as I don't usually read this group (yet).

Thanks in advance,

		Sincerely yours,

		Saul Lubkin

P.S.  Is there some (standard or not) on line manual of Postscript
commands in the public domain that one can download?
