Mostly Distiller 5.0, yes, and quite a few by Distiller 4.0 for Macintosh too. The sampling is quite random, I wrote a "robot" that automatically downloadsPDF files from the Web using Google search. I guess I wil just add a special provision to my parser to ignore the word "def" in Postscript streams. Thanks for your help.
