This is a list of all errors in the September 1978 TEX user manual that
were known on November 4, 1978. It also includes a few things that were
omitted in September. All these changes (and only these) have been
incorporated into the November 1978 manual.

Title page, change date to "November 1978 (second printing)" and change "draft" to
"drafts" in the first line of the footnote.

Page 26, line 4, delete "of the second paragraph".

Page 29, line 13, change "later.)" to "later. A list of control sequences for
special symbols appears in Appendix F.)

Page 40, line 15
(one centimeter equals 26.600 Didot points)

Page 32, line 18, change "11" to "12".

Page 59, line 4, insert a ")" after this line.

Page 61, line 28, insert a "$" before the pound sterling sign

Page 61, line 30, change ", and" to ", ``$\$$'', and"

Page 82, line 13, append this to the paragraph: "Another case is a formula
like n/log n, where a negative thin space has been inserted after the /.)".

Page 102, line 6, append this to the paragraph: "The control sequences
\vcenter and \vtop are also useful for box positioning (see Chapter 26)."

Page 106, line 17, change "instead of ``$\ctr{#}$''" to "instead of ``\ctr{$#$}''".

Page 106, last three lines, change "processed; you might ... appropriate \def." to
"processed.".

Page 135, change the first 7 lines to the following:

  based only on the current style, regardless of the sizes of numerator and
  denominator.

    / \vcenter \
  ⊗<            >{<vlist>}      Append a centered or top-adjusted box.
    \   \vtop  /
  The specified vertical list is constructed in restricted vertical mode, then
  it is \vjusted and the resulting box is moved up or down so that (\vcenter) it is
  centered vertically just as large delimiters are, or (\vtop) the baseline of the
  topmost box in the vertical list coincides with the baseline of the formula.
  Then TEX resumes its activities in math mode.

Page 158, line 16, change ". (We" to ".\xskip (We".

Page 158, new paragraph inserted before the 4th-last line on this page:
   ⊗ Within a paragraph, type ``\xskip'' before and after parenthesized sentences.
  (For example, there is an \xskip in the paragraph you are now reading, and in
  algstep E1 above.)

(The convention just explained has also been introduced into the entire TEX manual.)

Page 159, replace last two paragraphs by one paragraph, to wit:
     If the exercise contains a ``hint'' within a paragraph, you type
  ``\xskip[{\sl Hint:} ''; as usual, there should be no space before \xskip.

Page 162, line 4, change "Addison-Wesley's" to "the publisher's".

Page 165, line 15, change "4.5" to "4.625".

Page 165, line 23, change "4" to "4.25".

Page 182, line 6, change "or XYZages" to "XYZages, or XYZest"

Page 182, lines 14 and 15, change "-xe, or -xye, where x and y" to
	"-Xe, or -XYe, where X and Y"

Page 182, line 18, new sentence appended to this paragraph:
	"Similarly, final syllables of the form -Xed or -XYed (except -ized)
	are also disregarded."

Page 185, line 22, delete "guess-work"

Page 186, line 7, change "prob-a-bil-ity" to "prob-abil-ity".

Page 187, index entry for Bibliographic..., change "14" to "15".

Page 189, index entry for \deg, add page 164.

Page 195, delete 15th line in left-hand column.

Page 195, index entry for \spose, add page 39.

Page 196, index entry for \vcenter, add page 102.

Page 196, new index entry:
  \vtop (make <vlist> box using top baseline), 102, 135.

Page 196, index entry for \xskip, change "159" to "158--160".

Page 196, index entries for \yskip and \yyskip, change "158--159" and "158"
to "159".

Page 197, index entry for \$, add page 61.

Page 198, the TEX logo is too small, each time it appears on this page.
Extensions to TEX made since the November printing of the manual:

1. There is a new <dimenparam> in addition to \hsize, \vsize, \maxdepth, etc.,
namely \mathsurround. By typing "\mathsurround <dimen>" you specify an amount
of blank space that appears to the left and right of any formula that appears
in text (i.e., formulas delimited by $ and $).

2. There is a new option to \advcount: If you type "\advcount <digit> by <number>"
the specified counter is increased by the specified number. (When the "by" option
is omitted, the counter is increased by plus-or-minus one as presently.)
For example, "\advcount 0 by - \count 1" subtracts counter 1 from counter 0.

3. The control sequence \unskip can be used in horizontal mode (or restricted
horizontal mode) to delete one glob of glue, if this glue was the last item
added to the horizontal list. The main use of this is to remove an unwanted space
that may have just appeared. For example, in a macro expansion the string
"#1\unskip" denotes parameter #1 with a final blank space (or other glue) removed,
if #1 ends with a blank space (or other glue).

4. Typing "\uppercase{<token list>}" in horizontal mode will change all lower-case
letters of the token list into upper case. (But not the letters of control
sequences.) Similarly, "\lowercase{<token list>}" changes upper-case letters
into lower case.

5. Typing "\xdef<control sequence>{<result text>}" is like
"\gdef<control sequence>{<result text>}" except that definitions in the result
text are expanded. For example, "\xdef\z{\z\y}" will append the current result
text of macro \y to the current result text of macro \z.
Corrections noted since the November printing:

Page 145, a new error message:
Warning: Long input line has been broken.
Your input file contained a very long sequence of characters between
carriage returns. TEX arbitrarily broke it after 150 characters.
