RS/6000 dpsexec window control

[Keith Rich]

I am using /usr/lpp/DPS/bin/dpsexec to do Postscript previewing, but
I don't know how to make it start up with a bigger window positioned
in a specific place on the screen.  I'd like to initiate this from
a shell script such that most of the screen does the previewing.
Has anyone done this?  If so, how do you say the equivalent of
"dpsexec -geometry mumble etc." (on RS/6000 AIX 3.1 3002)?
