Posting-number: Volume 24, Issue 1
Archive-name: zsh2.1/part01
Environment: BSD
Supersedes: zsh2.00: Volume 18, Issue 84-98

This is zsh 2.1.0, written by Paul Falstad ([e-mail]).
I've tested it on the following machines, where it compiled just by running
a shell script:

Sun SPARCServer 4/490 running SunOS 4.1.1
NeXTstation running Mach 2.0
DECSystem-5000 running ULTRIX 4.2
Sun 3/50M running SunOS 4.0
Iris 4D/20 running IRIX 3.3.1
Tahoe running BSD 4.3 tahoe
HP 9000/855 running HP-UX 8.0
HP 9000/370 running HP-UX 7.05

It should be easier to port the shell to different architectures now.
The reason it won't run on SysV-like machines is that I don't have
access to any SysV-like machines.  I'd love to have someone help port the
shell to other architectures.

Basically, zsh is a shell with most of the features of tcsh, ksh,
and bash, plus a few more.  The input syntax is mostly ksh-like, though
csh syntax is also accepted in most cases; plus, almost all of the
bells and whistles of other shells have been included.

A PostScript version of "An Introduction to the Z Shell" has also been
included with this distribution.

You can ftp the distribution (or just the introduction) from cs.ucsd.edu
(132.239.51.3) as "/pub/zsh/{zsh2.1.0.tar.Z,intro.ps.Z}".

This version supersedes zsh2.0.?.  Major changes in this version:

1. Parser was rewritten and improved.  All the old syntax is still
accepted, with the addition of some other command forms.

2. Almost all known bugs (from previous releases) have been fixed.  It
won't sit around after the connection closes anymore.  It won't die
if you press TAB inside a `...` expression.  It won't mangle your
tty settings, since it doesn't fiddle with the tty as much.  Plus,
lots of little bugs have been fixed.

3. The completion has been improved; hostname completion is supported
now.  If you give the shell a list of hosts, you can type
"telnet hostn[tab]" and it will complete the hostname.  Plus you can
say "bindkey control-whatever forward-w[tab]", and "vared PRO[tab]",
and "echo $PRIN[tab]", and "setopt cshnul[tab]", and
"mail foobar@foohos[tab]", etc.

4. vi-mode emulation has been improved.  All the fancy stuff is there,
like multiple buffers and repeat-last-change, and a real insert mode.

X            GNU GENERAL PUBLIC LICENSE
X             Version 1, February 1989
X
X Copyright (C) 1989 Free Software Foundation, Inc.
X                    675 Mass Ave, Cambridge, MA 02139, USA
X Everyone is permitted to copy and distribute verbatim copies
X of this license document, but changing it is not allowed.
X
X                Preamble
X
X  The license agreements of most software companies try to keep users
Xat the mercy of those companies.  By contrast, our General Public
XLicense is intended to guarantee your freedom to share and change free
Xsoftware--to make sure the software is free for all its users.  The
XGeneral Public License applies to the Free Software Foundation's
Xsoftware and to any other program whose authors commit to using it.
XYou can use it for your programs, too.
X
X  When we speak of free software, we are referring to freedom, not
Xprice.  Specifically, the General Public License is designed to make
Xsure that you have the freedom to give away or sell copies of free
Xsoftware, that you receive source code or can get it if you want it,
Xthat you can change the software or use pieces of it in new free
Xprograms; and that you know you can do these things.
X
X  To protect your rights, we need to make restrictions that forbid
Xanyone to deny you these rights or to ask you to surrender the rights.
XThese restrictions translate to certain responsibilities for you if you
Xdistribute copies of the software, or if you modify it.
X
X  For example, if you distribute copies of a such a program, whether
Xgratis or for a fee, you must give the recipients all the rights that
Xyou have.  You must make sure that they, too, receive or can get the
Xsource code.  And you must tell them their rights.
X
X  We protect your rights with two steps: (1) copyright the software, and
X(2) offer you this license which gives you legal permission to copy,
Xdistribute and/or modify the software.
X
X  Also, for each author's protection and ours, we want to make certain
Xthat everyone understands that there is no warranty for this free
Xsoftware.  If the software is modified by someone else and passed on, we
Xwant its recipients to know that what they have is not the original, so
Xthat any problems introduced by others will not reflect on the original
Xauthors' reputations.
X
X  The precise terms and conditions for copying, distribution and
Xmodification follow.
X
X            GNU GENERAL PUBLIC LICENSE
X   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
X
X  0. This License Agreement applies to any program or other work which
Xcontains a notice placed by the copyright holder saying it may be
Xdistributed under the terms of this General Public License.  The
X"Program", below, refers to any such program or work, and a "work based
Xon the Program" means either the Program or any work containing the
XProgram or a portion of it, either verbatim or with modifications.  Each
Xlicensee is addressed as "you".
X
X  1. You may copy and distribute verbatim copies of the Program's source
Xcode as you receive it, in any medium, provided that you conspicuously and
Xappropriately publish on each copy an appropriate copyright notice and
Xdisclaimer of warranty; keep intact all the notices that refer to this
XGeneral Public License and to the absence of any warranty; and give any
Xother recipients of the Program a copy of this General Public License
Xalong with the Program.  You may charge a fee for the physical act of
Xtransferring a copy.
X
X  2. You may modify your copy or copies of the Program or any portion of
Xit, and copy and distribute such modifications under the terms of Paragraph
X1 above, provided that you also do the following:
X
X    a) cause the modified files to carry prominent notices stating that
X    you changed the files and the date of any change; and
X
X    b) cause the whole of any work that you distribute or publish, that
X    in whole or in part contains the Program or any part thereof, either
X    with or without modifications, to be licensed at no charge to all
X    third parties under the terms of this General Public License (except
X    that you may choose to grant warranty protection to some or all
X    third parties, at your option).
X
X    c) If the modified program normally reads commands interactively when
X    run, you must cause it, when started running for such interactive use
X    in the simplest and most usual way, to print or display an
X    announcement including an appropriate copyright notice and a notice
X    that there is no warranty (or else, saying that you provide a
X    warranty) and that users may redistribute the program under these
X    conditions, and telling the user how to view a copy of this General
X    Public License.
X
X    d) You may charge a fee for the physical act of transferring a
X    copy, and you may at your option offer warranty protection in
X    exchange for a fee.
X
XMere aggregation of another independent work with the Program (or its
Xderivative) on a volume of a storage or distribution medium does not bring
Xthe other work under the scope of these terms.
X
X  3. You may copy and distribute the Program (or a portion or derivative of
Xit, under Paragraph 2) in object code or executable form under the terms of
XParagraphs 1 and 2 above provided that you also do one of the following:
X
X    a) accompany it with the complete corresponding machine-readable
X    source code, which must be distributed under the terms of
X    Paragraphs 1 and 2 above; or,
X
X    b) accompany it with a written offer, valid for at least three
X    years, to give any third party free (except for a nominal charge
X    for the cost of distribution) a complete machine-readable copy of the
X    corresponding source code, to be distributed under the terms of
X    Paragraphs 1 and 2 above; or,
X
X    c) accompany it with the information you received as to where the
X    corresponding source code may be obtained.  (This alternative is
X    allowed only for noncommercial distribution and only if you
X    received the program in object code or executable form alone.)
X
XSource code for a work means the preferred form of the work for making
Xmodifications to it.  For an executable file, complete source code means
Xall the source code for all modules it contains; but, as a special
Xexception, it need not include source code for modules which are standard
Xlibraries that accompany the operating system on which the executable
Xfile runs, or for standard header files or definitions files that
Xaccompany that operating system.
X
X  4. You may not copy, modify, sublicense, distribute or transfer the
XProgram except as expressly provided under this General Public License.
XAny attempt otherwise to copy, modify, sublicense, distribute or transfer
Xthe Program is void, and will automatically terminate your rights to use
Xthe Program under this License.  However, parties who have received
Xcopies, or rights to use copies, from you under this General Public
XLicense will not have their licenses terminated so long as such parties
Xremain in full compliance.
X
X  5. By copying, distributing or modifying the Program (or any work based
Xon the Program) you indicate your acceptance of this license to do so,
Xand all its terms and conditions.
X
X  6. Each time you redistribute the Program (or any work based on the
XProgram), the recipient automatically receives a license from the original
Xlicensor to copy, distribute or modify the Program subject to these
Xterms and conditions.  You may not impose any further restrictions on the
Xrecipients' exercise of the rights granted herein.
X
X  7. The Free Software Foundation may publish revised and/or new versions
Xof the General Public License from time to time.  Such new versions will
Xbe similar in spirit to the present version, but may differ in detail to
Xaddress new problems or concerns.
X
XEach version is given a distinguishing version number.  If the Program
Xspecifies a version number of the license which applies to it and "any
Xlater version", you have the option of following the terms and conditions
Xeither of that version or of any later version published by the Free
XSoftware Foundation.  If the Program does not specify a version number of
Xthe license, you may choose any version ever published by the Free Software
XFoundation.
X
X  8. If you wish to incorporate parts of the Program into other free
Xprograms whose distribution conditions are different, write to the author
Xto ask for permission.  For software which is copyrighted by the Free
XSoftware Foundation, write to the Free Software Foundation; we sometimes
Xmake exceptions for this.  Our decision will be guided by the two goals
Xof preserving the free status of all derivatives of our free software and
Xof promoting the sharing and reuse of software generally.
X
X                NO WARRANTY
X
X  9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
XFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
XOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
XPROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
XOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
XMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
XTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
XPROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
XREPAIR OR CORRECTION.
X
X  10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
XWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
XREDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
XINCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
XOUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
XTO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
XYOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
XPROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
XPOSSIBILITY OF SUCH DAMAGES.
X
X             END OF TERMS AND CONDITIONS
X
X    Appendix: How to Apply These Terms to Your New Programs
X
X  If you develop a new program, and you want it to be of the greatest
Xpossible use to humanity, the best way to achieve this is to make it
Xfree software which everyone can redistribute and change under these
Xterms.
X
X  To do so, attach the following notices to the program.  It is safest to
Xattach them to the start of each source file to most effectively convey
Xthe exclusion of warranty; and each file should have at least the
X"copyright" line and a pointer to where the full notice is found.
X
X    <one line to give the program's name and a brief idea of what it does.>
X    Copyright (C) 19yy  <name of author>
X
X    This program is free software; you can redistribute it and/or modify
X    it under the terms of the GNU General Public License as published by
X    the Free Software Foundation; either version 1, or (at your option)
X    any later version.
X
X    This program is distributed in the hope that it will be useful,
X    but WITHOUT ANY WARRANTY; without even the implied warranty of
X    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
X    GNU General Public License for more details.
X
X    You should have received a copy of the GNU General Public License
X    along with this program; if not, write to the Free Software
X    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
X
XAlso add information on how to contact you by electronic and paper mail.
X
XIf the program is interactive, make it output a short notice like this
Xwhen it starts in an interactive mode:
X
X    Gnomovision version 69, Copyright (C) 19xx name of author
X    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
X    This is free software, and you are welcome to redistribute it
X    under certain conditions; type `show c' for details.
X
XThe hypothetical commands `show w' and `show c' should show the
Xappropriate parts of the General Public License.  Of course, the
Xcommands you use may be called something other than `show w' and `show
Xc'; they could even be mouse-clicks or menu items--whatever suits your
Xprogram.
X
XYou should also get your employer (if you work as a programmer) or your
Xschool, if any, to sign a "copyright disclaimer" for the program, if
Xnecessary.  Here a sample; alter the names:
X
X  Yoyodyne, Inc., hereby disclaims all copyright interest in the
X  program `Gnomovision' (a program to direct compilers to make passes
X  at assemblers) written by James Hacker.

XThis is zsh 2.1.0, written by Paul Falstad ([e-mail]).
X
XTo get this shell running, cd into the src directory and type
X"buildzsh".  I tested it on the following machines, where it compiled
Xjust by running this script:
X
XSun SPARCServer 4/490 running SunOS 4.1.1
XNeXTstation running Mach 2.0
XDECSystem-5000 running ULTRIX 4.2
XSun 3/50M running SunOS 4.0
XIris 4D/20 running IRIX 3.3.1
XTahoe running BSD 4.3 tahoe
XHP 9000/855 running HP-UX 8.0
XHP 9000/370 running HP-UX 7.05
X
XIt should be easier to port the shell to different architectures now.
XThe reason it hasn't been tested on SysV-like machines is that I don't
Xhave access to any SysV-like machines.  I'd love to have someone port
Xthe shell to other architectures.
X
XTabstops are 3 spaces.  If you're going to look at my code, run it
Xthough "expand -3" first, or set your tab stops to the same as mine.
X
XIf anyone has any questions, suggestions, comments, bugs, flames, or
Xany other mail of any kind, send it to [e-mail].

XModification history:
X
X0.03-1.0:
X    - "..../" is now "****/".  I know this isn't backward compatible,
X      but I had no choice; the string "..../" was unquotable.
X    - parser was rewritten and improved
X    - completion was improved, several bugs fixed (including
X      the "$([tab]" bug)
X    - vi mode editing is improved
X    - the value of PWD and OLDPWD in the environment now change
X    - the PROMPT formatting strings %W and %D now print the month
X      correctly
X    - >&2 echo "error message" no longer prints "bad file number"
X    - ${foo%pat} no longer alters the value of foo
X    - $_ works
X    - ALL_EXPORT no longer causes let statements to crash the shell
X    - continue works
X    - echo $MAIL no longer dumps core if MAIL is null
X    - the new tty driver is selected by default
X    - the s modifier no longer complains if it can't find the string
X      to substitute
X    - list-choices no longer fignores files
X    - cd is now smarter about symlinks
X    - negative subscripts other than -1 now work
X    - $(<filename) works better if filename contains $, ~, or =
X    - rehash no longer wastes memory
X    - with name=value assignments, name is checked to see if it is
X      a valid identifier
X    - !1; !2 no longer eats the semicolon
X    - $foo:h never returns the empty string if foo starts with /
X    - select crashed with some compilers
X    - problems with aliases in <(...) constructs have been fixed
X    - links pointing to nowhere are denoted with an '&' in listtypes
X    - negative arguments are supported
X    - the shell does not screw around with the tty so much
X    - lots of other stuff
X
X0.02-0.03:
X    - two stupid bugs that were introduced in the last patch were fixed:
X      - multiple command substitution on a line failed
X      - a file descriptor leak caused the shell to crash after a while
X    - added 'An Introduction to the Z Shell'
X    - behaves properly when the tty session dies suddenly
X    - had a serious memory leak on some systems
X    - the test and [ builtins have been added, although [[...]]
X      is more efficient
X    - in your prompt, %m2 now prints foo.bar, %m3 prints foo.bar.com, etc.
X    - the -D and -P options to print have been added
X    - the NULLCMD and ZDOTDIR parameters have been added
X    - ${*:-foo} works
X    - "$@" and "$arr[@]" work like ksh
X    - .zprofile is sourced before .zshrc in login shells
X    - the CSHJUNKIEQUOTES and PUSHDMINUS options have been added
X    - REAL_TTY compilation switch added
X    - aliases beginning with a space cause the history line to be junked
X      if HISTIGNORESPACE is set
X    - echo prints bad options instead of complaining about them
X    - "set -o" no longer dumps core
X    - "alias a=alias; date >a" no longer creates a file called "alias"
X    - "function foo() \n { date }" is now legal (the () and the newline
X      are allowed)
X    - nested brace expressions work properly
X    - disabled commands stay disabled after a rehash (or after the shell
X      finishes sourcing your .zshrc)
X    - corrected aliases work
X    - executables in the currect directory are now completed
X    - in "case foo", "foo" is not interpreted as a directory name with autocd
X    - aliases were not always interpreted properly after a completion
X    - bindkey '^?' didn't work
X    - echo ${HOST:-{bar}} didn't work
X    - editor update is more efficient in some cases
X    - menucomplete works even better
X    - assign to an array element "foo[1]=bar" didn't always work
X    - doesn't print directories like "~tmp" if HOME=/
X    - quotes in case statement patterns caused problems
X    - pressing ^C right after typing "fc" caused the editor to share
X      the tty with the shell
X    - echo $(echo 2) produced no output, but echo $(echo x) worked fine (weird)
X
X0.01-0.02:
X    - added script to convert most csh aliases to zsh aliases or functions
X    - fc -l (history) now appears in the history itself; HISTNOSTORE
X      option added to get old behavior
X    - the POSIX process group race has been fixed; so 'w | more' should
X      no longer hang
X    - FCEDIT added, to match the documentation
X    - %{...%} in the prompt added
X    - execute-named-cmd and execute-last-named-cmd bindings added
X    - sources ~/.zshenv in all shells, even if not interactive, unless
X      -f is given
X    - ^ and # are no longer `magic' by default; use EXTENDEDGLOB option
X      to use them
X    - now checks for tty sanity before each command
X    - if the right side of a variable assignment expands to more than
X      one word, array assignment is assumed; so foo=*.c now works
X    - ~foo is no longer expanded in completion
X    - select now works even if the argument list is not sorted
X    - menucompletebeep option added
X    - emacs mode is now 8-bit clean by default; use bindkey -em
X      to get your meta key back
X    - fc -R, fc -W added
X    - nocorrect added
X    - lines from history file are now split into words at spaces
X    - glob-complete, accept-and-menu-complete,
X      beginning-of-line-hist, end-of-line-hist bindings added
X    - insert-last-word bound to M-. in emacs mode by default; now moves
X      back through the history if run repeatedly
X    - J and K now bound to history search in vi mode
X    - delete-char no longer core dumps on an empty line
X    - menu-complete works better
X    - the editor checks the settings of VISUAL and EDITOR to set
X      default bindings
X    - using [[ ... ]] expressions on a symbolic link works as expected
X    - various problems with globbing were fixed
X    - xx is now the same as !! if HISTCHARS=x
X    - added config.h entry for compilers that don't know about void *
X    - lexical analysis made more efficient
X    - "if echo $? ; then : ; fi" no longer always prints 0
X    - removed all enums, '\x7f's from code
X    - in "case foo in bar) xxx ;; esac", foo and bar are no longer subject
X      to command alias expansion
X    - works on platforms where toupper('A') != 'A'
X    - \e sequence added to echo
X    - + options now work with set
X    - AUTORESUME and AUTOCD work better
X    - getopts works better (?)
X    - spell checking works better
X    - "let 2+3=" no longer crashes the shell
X    - "foo=bar; echo ${=foo}" no longer crashes the shell
X    - "zsh -c" or "zsh -o" no longer causes a core dump
X    - "unset MAIL; echo $MAIL" no longer causes a core dump
X    - "(xterm&xterm&)&" no longer causes a core dump
X    - "echo $HOM[tab]" beeps instead of deleting "$HOM"
X    - incremental history search works better
X    - the pwd of a fg'd job is now printed _before_ resuming it
X    - rv=`echo -n foo` no longer puts garbage in $rv
X    - "=1/*" now works as expected

X    - $status added for csh compatibility
X    - arrays are automatically expanded if you say 'foo[1234]=x'
X    - shell now ignores SIGQUIT (it was commented out before :-)
X    - the times builtin works on systems where times() returns > 0
X    - no longer hangs the terminal if you ^S before flow control
X      is turned off
X    - "date ; read foo" now works in interactive shells

X    - if the cursor is at the end of the line, vi-cmd-mode
X      moves it back one position.
X    - delete-char now acts more like x in vi.
X    - a "prompt" parameter has been added, which is equivalent to
X      PROMPT and PS1.
X    - zsh no longer expands symbolic links.  The CHASELINKS option
X      has been provided to get the old behavior.
X    - history searches ignore lines that are the same as the line

X.TH ZSH 1 "1991 Oct 17"
X.SH NAME
Xzsh \- the Z shell
X.SH SYNOPSIS
X\fBzsh\fP [ \(+-\fIoptions\fP ] [ \(+-\fBo\fP \fIoption\fP ] ...  [ \-\fBc\fP \fIstring\fP ] [ \fIarg\fP ... ]
X.SH "SHELL GRAMMAR"
XA \fIsimple command\fP is a sequence of optional parameter
Xassignments followed by blank-separated words,
Xwith optional redirections interspersed.
XThe first word is the command to be executed, and the remaining
Xwords, if any, are arguments to the command.
XIf a command name is given, the parameter assignments modify
Xthe environment of the command when it is executed.
XThe value of a simple command is its exit status,
Xor 128 plus the signal number if terminated by a signal.
X.PP
XIf a simple command is preceded by the word \fBexec\fP,
Xit is executed in the parent shell without forking.
XIf preceded by \fBcommand\fP, the command word is taken
Xto be the name of an external command, rather than a
Xshell function or builtin.
XIf preceded by \fBnoglob\fP, filename generation is not performed
Xon any of the words.  If preceded by a \-, the command
Xis executed with a \- prepended to its \fBargv[0]\fP string.
XIf preceded by \fBnocorrect\fP, spelling correction is not
Xdone on any of the words.
X.PP
XA \fIpipeline\fP is a sequence of one or more commands
Xseparated by \fB|\fP or \fB|&\fP.  \fB|&\fP is shorthand
Xfor \fB2>&1 |\fP.  The standard output of each command is
Xconnected to the standard input of the next command in the
Xpipeline.
X.PP
XThe value of a pipeline is the value of the last command.
XIf a pipeline is preceded by a \fB!\fP, the value
Xof that pipeline is the logical NOT of the value of the last
Xcommand.
X.PP
XIf a pipeline is preceded by \fBcoproc\fP, it is
Xexecuted as a coprocess; a two-way pipe is established
Xbetween it and the parent shell.  The shell can read from or write to
Xthe coprocess by means of the \fB>&p\fP and \fB<&p\fP
Xredirection operators.
X.PP
XA \fIsublist\fP is a sequence of one or more pipelines
Xseparated by \fB&&\fP or \fB|\||\fP.  If two pipelines
Xare separated by \fB&&\fP, the second pipeline is executed
Xonly if the first is successful (returns a zero value).
XIf two pipelines are separated by \fB|\||\fP, the second is executed
Xonly if the first is unsuccessful (returns a nonzero value).
X.PP
XA \fIlist\fP is a sequence of one or more sublists
Xseparated by, and optionally terminated by, \fB;\fP, \fB&\fP,
Xor a newline.
XNormally the shell waits for each list to finish before executing
Xthe next one.
XIf a list is terminated by a \fB&\fP, the shell executes
Xit in the background, and does not wait for it to finish.
X.PP
XA \fIcomplex command\fP is one of the following:

X.PD
XExpand the list of \fIword\fPs, and set the parameter
X\fIname\fP to each of them in turn, executing
X\fIlist\fP each time.  If the \fBin\fP \fIword\fP is omitted,
Xuse the positional parameters instead of the \fIword\fPs.
X.TP
X\fBfor\fP \fIname\fP [ \fBin\fP \fIword\fP ... ] ; \fIsublist\fP
XThis is a shorthand for \fBfor\fP.

XThe \fBPROMPT3\fP prompt is printed and a line is read from standard
Xinput.  If this line consists of the number of one of the listed
X\fIword\fPs, then the parameter \fIname\fP
Xis set to the \fIword\fP corresponding to this number.
XIf this line is empty, the selection list is printed again.
XOtherwise, the value of the parameter \fIname\fP is set to null.
XThe contents of the line read from standard input is saved
Xin the parameter \fBREPLY\fP.  \fIlist\fP is executed
