 90 pages long, and barely described the original, "old" version of awk. After substantial revision, the first version of the The GAWK Manual to be released was Edition 0.11 Beta in October of 1989. The manual then underwent more substantial revision for Edition 0.13 of December 1991. David Trueman, Pat Rankin, and Michal Jaegermann contributed sections of the manual for Edition 0.13. That edition was published by the FSF as a bound book early in 1992. Since then there have been several minor revisions, notably Edition 0.14 of November 1992 that was published by the FSF in January of 1993, and Edition 0.16 of August 1993.

Edition 1.0 of AWK Language Programming represents a significant re-working of The GAWK Manual, with much additional material. The FSF and I agree that I am now the primary author. I also felt that it needed a more descriptive title.

AWK Language Programming will undoubtedly continue to evolve. An electronic version comes with the distribution from the FSF. If you find an error in this book, please report it! See section Reporting Problems and Bugs, for information on submitting problem reports electronically, or write to me in care of the FSF.

I would like to acknowledge Richard M. Stallman, for his vision of a better world, and for his courage in founding the FSF and starting the GNU project.
