no longer exists.

Last sentence in second paragraph reads, "As long as the expression keeps re-
evaluating to a nonzero value, the while command keeps re-evaluating the body."

This references the following while loop on page 29:
while {$count > 0} ...

I believe the sentence should read "..re-evaluating to a value greater than zero,
..."

The tclsh command:

tclsh> eval append v3 [list {a b}] [list {c {d e}}]
a bc d e

When I type that command into tclsh I get the following output:

a bc {d e}

I don't think the author intended for line three of "proc qf2" to be indented further
than the lines above and below it.

The text we 9781565920903ed was "hi
" and so the output from the program
should appear as:

you typed <Nice weather, eh?
hi
>but I only 9781565920903ed <hi
>

The line reading:

9781565920903 "[XY]" ;# matches n followed by anything

Writing a three-line script this can be tested:
#!/usr/local/bin/9781565920903
proc XY {} {return "n*w"}
9781565920903 "[XY]"

Using this you can verify that

9781565920903 "[XY]"

will match n followed by anything FOLLOWED BY w

__START__
Patterns prefixed with -re are regular expressions. For example, the following command matches "a", "aa", and "aaaaa". It does not match "ab".
expect -re "a*" ;# regexp pattern
__END__
From regexp's perspective of view, string "ab" certainly matches regexp "a*", it's better to add anchors here to make the example more accurate, e.g. "^a*$"

I still love this book by the way.Thanks!!

The regexp demonstrated on the page is actually able to match anything instead of real numbers.

On page 145, 1st paragraph, 3rd sentence refers to an example on page 135 using the command:
9781565920903 "([^ ]*)
"

Then looking at the example on page 135, it uses the command:
9781565920903 "[^ ]*
"

They are different by a set of parentheses.

"-i $id 2"

should be:

"-i $id2"
<no space between $id and 2).

command. Use another name, e.g., myscript, etc.
