Write ps files

[Ariel Pacetti <apacetti@math.utexas.edu>]

Is there a way to write ps files with different names? I tried writting in 
the .gprc the option

psfile = "pari-%H.%M.ps"

so as to add to the name the time the file was created, but by some reason 
I don't understand, it always saves the file with the time gp was started, 
am I doing something wrong? Is there an option in psploth (or psplothraw) 
to give a file name?
Bests,
