The quasi-definition of defineuserobject on p. 400 of the PostScript Language Reference Manual (Second Edition) is: userdict /UserObjects get 3 -1 roll put Am I right in thinking that the second line should be 3 1 roll put ?

Interestingly, this error is also in the Display PostScript System Reference manual, but nobody has ever noticed it. As far as I know, this is the first substantive error anyone has found in the new red book (though we've already spotted dozens of nits). Perhaps Adobe should award you some sort of prize.

He paid $0.01 for the first error, $0.02 for the second, doubling the reward for each new bug discovered. Of course you must have great confidence in the quality of the system or you can get into trouble. Knuth himself has done pretty well, last I heard the prize was only up to $20.48 (or maybe $40.96), and this is after some 10-12 years, I think.

The rate was $327.68 last year, but I don't know whether Don intends to double it again this year. Of course, this is for bugs in the program TeX, you get something much smaller (maybe $20.48) for bugs in the TeXbook. Now if Adobe would pay for bugs in their PostScript interpreters, we could all be rich :-) :-) :-) Chris Thompson JANET: cet1@uk.ac.cam.phx Internet: cet1%phx.cam.ac.uk@nsfnet-relay.ac.uk
