  10 '\" The definitions below are for supplemental macros used in Tcl/Tk
  11 '\" manual entries.
  12 '\"
  13 '\" .AP type name in/out ?indent?
  14 '\"     Start paragraph describing an argument to a library procedure.
  15 '\"     type is type of argument (int, etc.), in/out is either "in", "out",
  16 '\"     or "in/out" to describe whether procedure reads or modifies arg,
  17 '\"     and indent is equivalent to second arg of .IP (shouldn't ever be
  18 '\"     needed;  use .AS below instead)
  19 '\"
  20 '\" .AS ?type? ?name?
  21 '\"     Give maximum sizes of arguments for setting tab stops.  Type and
  22 '\"     name are examples of largest possible arguments that will be passed
  23 '\"     to .AP later.  If args are omitted, default tab stops are used.
  24 '\"
  25 '\" .BS
  26 '\"     Start box enclosure.  From here until next .BE, everything will be
  27 '\"     enclosed in one large box.
  28 '\"
  29 '\" .BE
  30 '\"     End of box enclosure.
  31 '\"
  32 '\" .CS
  33 '\"     Begin code excerpt.
  34 '\"
  35 '\" .CE
  36 '\"     End code excerpt.
  37 '\"
  38 '\" .VS ?version? ?br?
  39 '\"     Begin vertical sidebar, for use in marking newly-changed parts
  40 '\"     of man pages.  The first argument is ignored and used for recording
  41 '\"     the version when the .VS was added, so that the sidebars can be
  42 '\"     found and removed when they reach a certain age.  If another argument
  43 '\"     is present, then a line break is forced before starting the sidebar.
  44 '\"
  45 '\" .VE
  46 '\"     End of vertical sidebar.
  47 '\"
  48 '\" .DS
  49 '\"     Begin an indented unfilled display.
  50 '\"
  51 '\" .DE
  52 '\"     End of indented unfilled display.
  53 '\"
  54 '\" .SO
  55 '\"     Start of list of standard options for a Tk widget.  The
  56 '\"     options follow on successive lines, in four columns separated
  57 '\"     by tabs.
  58 '\"
  59 '\" .SE
  60 '\"     End of list of standard options for a Tk widget.
  61 '\"
  62 '\" .OP cmdName dbName dbClass
  63 '\"     Start of description of a specific option.  cmdName gives the
  64 '\"     option's name as specified in the class command, dbName gives
  65 '\"     the option's name in the option database, and dbClass gives
  66 '\"     the option's class in the option database.
  67 '\"
  68 '\" .UL arg1 arg2
  69 '\"     Print arg1 underlined, then print arg2 normally.

 249 .SH NAME
 250 lindex \- Retrieve an element from a list
 251 .SH SYNOPSIS
 252 \fBlindex \fIlist index\fR
 253 .BE
 254
 255 .SH DESCRIPTION
 256 .PP
 257 This command treats \fIlist\fR as a Tcl list and returns the
 258 \fIindex\fR'th element from it (0 refers to the first element of the list).
 259 In extracting the element, \fIlindex\fR observes the same rules
 260 concerning braces and quotes and backslashes as the Tcl command
 261 interpreter; however, variable
 262 substitution and command substitution do not occur.
 263 If \fIindex\fR is negative or greater than or equal to the number
 264 of elements in \fIvalue\fR, then an empty
 265 string is returned.
 266 If \fIindex\fR has the value \fBend\fR, it refers to the last element
 267 in the list, and \fBend\-\fIinteger\fR refers to the last element in
 268 the list minus the specified integer offset.
