I have a copy of Adobe's Postscript Language Manual, and there's not
a thing in it that mentions "dobits". I would assume that dobits is 
defined in the Laserprep, and that's it.  There is a section in the 
manual - the Postscript Cookbook - that has a program dealing with 
image operators and bit pattern screens (programs 19 & 20).
If you can't find a friend with a manual, Adobe systems Inc. is located
in Palo Alto, CA. Maybe jyou could call them up with questions on
obtaining a manual or help.
