That's a somewhat hard way, but it works (and requires no additional
money for programs!). I did things like that for years. You can also
use Illustrator to open a PS file and manipulate it in that program,
and then export it either as a bitmap or in a vector format.
I don't fiddle much with raw PS anymore for everyday manuals, though
sometimes it's useful to spit out PS from a C program to get just what
you want, or to do step and repeat. I created an artwork for checks
(cheques) that had thousands of tiny halftone logos on it. The
Imagesetter operator cancelled my job twice before I convinced him
that a 2K file could really take a few minutes to ouput (really to
execute, as PS is a real programming language). ;-)
(BTW, Illustrator has the stupidest way of creating arrays that I've
ever seen in any program)

Ha! A variation on the "if you can't make it good, make it RED"
"it's the network..." "The Journey is the reward"
