Might I ask why this old version (I haven't read it) instead of the manual/book for GNU awk? [1] It does a good job of mentioning differences between other implementations and GNU awk extensions are marked

That old version is written by the ‘A’[0], ‘W’[1], and ‘K’[2] that are the eponymous inventors of awk, and the book is at least occasionally cited as basically a masterpiece.[3]

I've also seen this book mentioned elsewhere but never took the effort of reading it. Hopefully I'll go through it sometime soon - it may be ~30 years old, but the core concepts is likely to work in gawk even now.

Also, the gawk book is written by Arnold Robbins who is one of current maintainers of the tool and as per [1] gawk was started by David Trueman and Arnold.

This book is not "an old version". This book is K&R-class. Moreover, the "K" is from the same person in both cases.
