Under "Pattern Globbing", the syntax {a,b,...} does not appear to apply

to Expect (I don't know if it works for Tcl).

Perhaps it would be a good idea to have a pointer in the Expect chapter to the
description of regular expressions and pattern globbing, since it is so
important to Expect.

wm resizeable window

the paragraph describes how to use wm resizeable window [widthBool
heightBool]. The error is with the "e" in resizeable it should be
resizable no "e". When I tried it with the "e" I recieved the following
error "Error: unknown or ambiguous option
"resizeable": must be aspect, client, command..."

expect

This entry is missing mention of the "-notransfer" option.

This option is described on page 154 of the book "Exploring Expect"
(11/96 edition).
Other missing options are: -indices (not sure if option -brace really
exists -- if it does, then it should also be listed as an option to the
interact command).

(Note: see pp. 531-536 of "Exploring Expect" for an accurate list of all
commands options.)

the options are completely incorrect for the commands

expect_after, expect_background, expect_before. The options for each of
these commands are the same:
- -all, -info, -noindirect . The verbiage for expect_background and
expect_before should say that the options are the same as for the expect_after
command.

command stty is missing options: < ttyname, raw, -raw, cooked, -cooked,

echo, -echo, rows [#], columns [#]. It also takes the same options as the stty
shell command (in addition to those explicitly listed in the last sentence).

Under the wait description, it omits explaining that "wait -i -1" will

clean up a zombie child created by fork (I spent a lot of time trying
workarounds before I realized this). Also, it should say "the current spawned
process is waited for" rather than "the current process is waited for".
