Hi all, Does anybody know if there exists an errata list for "Compilers:
Principles, Techniques and Tools" by Aho, Sethi and Ullman? I've checked
everywhere so far on the web but cannot find one.

I think I may have found a typo. It's not really that important (I don't
want to be pedantic), but so many people rave about what a near-perfect
book this is, that I'm not sure whether _I've_ missed something, or
whether this really is a genuine mistake. I think you know what I mean :)

Anyway, here is the suspected typo from page 87, line 8, just under the
heading "Attributes for Tokens":

"When more than one pattern matches a lexeme, the lexical analyzer
must provide additional information about the particular lexeme
that matched to the subsequent phases of the compiler."

should read:

"When a pattern matches more than one lexeme..."

What do you think?

Thanks for your help.

Andrew Nesbit
