This is not a problem at all.  If you are interested in what is sent
to gs, there is a simple trick:  Just temporarily replace the gs
binary by a script which redirects its input to a file.

Similarly, if you want to know with which arguments gv is invoked,
replace gs by a script like

#!/bin/sh
echo "$@"

and run gv.  And if you are debugging PostScript quite often, maybe
my little script

    http://ms25.ath.cx/stackdump.ps

is quite convenient.  It defines the procedure ?? which prints the
content of the stack to screen.  Try

  gs -q -dBATCH -dNODISPLAY stackdump.ps myfile.ps

where myfile.ps contains, for example:

   (hello) 1 2 ?? mul 3 4 ??

  Reinhard
