Well, you can set the histchars variable. See the csh man page.

with

are now in bold, as they are in section 6.

to "Printable characters (includes whitespace)"

Should read:

$ grep " ["[{(]*book[]})"?!.,;:'s]* " bookwords

(This change escapes the exclamation point. It's needed only if you use bash or csh as your shell.
At the time I wrote it, I was using ksh which doesn't have the problem.)

inserted as the first line:

#!/bin/sh

Also, the superfluous double quotes around "3" in the first line of the
script have been removed.

Also, as it's common practice to output usage & error messages to stderr.
The first two echo commands have been appended with >&2 as follows:

echo Usage: gres pattern replacement file >&2

and:

echo $3 is not a file. >&2

The gres command in the middle of the page used to read:

.Se 00 "Appendix"

It now reads:

.Se 00 "Full Program Listings"

global subsitution. The first one, for example, now reads:

s/pig/cow/g
s/cow/horse/g

The second one now reads:

s/cow/horse/g
s/pig/cow/g

now ends with a slash "/"

/^.Ah/{
s/.Ah */

@A HEAD = /
s/"//g
s/$/
/
}

/^.XX /s/sed, substitution command/sed, substitute command/

code example -2 also changed:

/^.XX /s/substitution/substitute/

.Rh 0 "DBclose" "closes a database"

sed -n "
/^.de *$mac/,/^..$/{
p
/^..$/q
}" $file

and:

/^..$/q

The "s" command is now lower case.

SHOULD BE:
"$!N"

that the sample now reads as follows:

John Robinson, 696-0987
Phyllis Chapman, 879-0900

2 records processed.

The last two lines on the page now read:

125 Market -125.45
126 Hardware Store -34.95

the amount spent on each item. Also, in the middle of the page, the
last 5 lines of code now read:

#2 Apply to each check record, adding amount from balance.
{ print $1, $2, $3
print balance += $3 # checks have negative amounts
}

"Here's the info script using awk:". The footnote text is

Remember that you need an awk that provides POSIX semantics for
this to work. It may be named awk, nawk, or even something else!
Check you local system documentation.

("awk" and "nawk" are in bold.)

if ( $i in acro ) {
# if it matches, add description
$i + acro[$i] " (" $i ")"
to
if ( $i in acro ) {
acronym =$i
# if it matches, add description
$i = acro[$i] " (" $i ")"

The second code block, fourth line read:

for (j - i; ARRAY[j-1] > ARRAY[j]; --j) {

but now reads:

for (j = i; (j-1) in ARRAY && ARRAY[j-1] >

now reads

awk -v CMDFILE="uucp_commands" script -

("script" is still constant-width italic font.)

(closed-up the space)

The ftp location for GNU awk has been updated. It now reads:

ftp.gnu.org

and

/gnu/gawk/gawk-3.0.3.tar.gz

Under "GNU awk (gawk)," second paragraph, line 2 read:

/gnu/gawk/gawk-3.0.3.tar.gz

It now reads:

/gnu/gawk/gawk-3.0.4.tar.gz

code sample, changed alignment so that it now reads:

a[1][1] = "hello"
a[1][2] = "world"
for (i in a [1])
print a[1][i]
