Non-bug suggestions (GAWK: Effective AWK Programming, Edition 3, June 2005)

[Jack Kelley]

Arnold (?),

I am working through 'GAWK: Effective AWK Programming' (Edition 3, June
2005). Very good stuff.

Here are a few typos/suggestions/queries for chapters 3 & 4.

###########################################################

3.7 Page 49 line -2: "FS is a set to" --> "FS is set to"

3.7 Page 50 par 2 line 2: "seperator" --> "separator"

3.7 Page 51 par 4 (RS==""): To agree with page 49 par -1, and page 50
par 1, should "The newline character always serves as a field separator,
in addition to whatever value FS may have" be qualified with "provided
only that FS is a (non-regexp) single character"? (I have not yet
experimented with this.)

3.8.1 Page 52 program line "t = -1" seems superfluous.

3.8.1 Page 52 line 1: "all C-style comments" --> "C-style comments"
                                           (would be more up-front)

3.8.7 Page 55 par 2 line 2: "gawk allows you start a coprocess"
                        --> "gawk allows you to start a coprocess"

4.5.2 Page 61 (%f): "and positive infinity as 'inf' and '-infinity'"
                --> "and positive infinity as 'inf' and 'infinity'"

4.5.2 Page 61 (%F): "not all systems support."
                --> "not all systems support it."

4.5.3 Page 62 par -1: "apostrohe" -> "apostrophe"

4.5.3 Pages 62-63: The comments
  Show source program
  Run it in "C" locale
  Run in US English UTF locale
are not prefixed by # and have hit the page margin and wrapped.

4.5.3 Page 63 (NOTE on the apostrophe flag):
"it now becomes difficult to use it in command-line programs" -->
"it becomes difficult to use in command-line programs"

4.6 Page 66 last sentence: "because awk requires" -->
"because (if you mean to refer to that same file or command) awk
requires"

4.6 Page 67 par 2: "See Section 10.2" -->
"See Section 3.8.7, page 55, for a brief discussion. See Section 10.2"

4.6 Page 67 pars 4, 5: The "common error" of par 4 becomes "isn't
necessary" in par 5. I agree, but does the example work anyway, and if
so, under what limitations?
