Hi James, *> **So I don't think it's an even comparison.*
Ralph's right. Awk, sed, and Perl can't programmatically change what syntax is used for comments, whereas Roff *can*: .ec A .de test This is a line. \" This is a comment .. .test The above snippet outputs: This is a line. \" This is a comment As you can see, comments can't be optimised away as "junk syntax", meaning the lexer/parser **has** to take them into consideration.
