'\" The definitions below are for supplemental macros used in Tcl/Tk
'\" manual entries.
'\"
'\" .AP type name in/out ?indent?
'\"	Start paragraph describing an argument to a library procedure.
'\"	type is type of argument (int, etc.), in/out is either "in", "out",
'\"	or "in/out" to describe whether procedure reads or modifies arg,
'\"	and indent is equivalent to second arg of .IP (shouldn't ever be
'\"	needed;  use .AS below instead)
'\"
'\" .AS ?type? ?name?
'\"	Give maximum sizes of arguments for setting tab stops.  Type and
'\"	name are examples of largest possible arguments that will be passed
'\"	to .AP later.  If args are omitted, default tab stops are used.
'\"
'\" .BS
'\"	Start box enclosure.  From here until next .BE, everything will be
'\"	enclosed in one large box.
'\"
'\" .BE
'\"	End of box enclosure.

'\"
'\" .CE
'\"	End code excerpt.
'\"
'\" .VS ?version? ?br?
'\"	Begin vertical sidebar, for use in marking newly-changed parts
'\"	of man pages.  The first argument is ignored and used for recording
'\"	the version when the .VS was added, so that the sidebars can be
'\"	found and removed when they reach a certain age.  If another argument
'\"	is present, then a line break is forced before starting the sidebar.
'\"
'\" .VE

'\"
'\" .DS
'\"	Begin an indented unfilled display.
'\"
'\" .DE
'\"	End of indented unfilled display.

'\"	options follow on successive lines, in four columns separated
'\"	by tabs.
'\"
'\" .SE
'\"	End of list of standard options for a Tk widget.
'\"
'\" .OP cmdName dbName dbClass
'\"	Start of description of a specific option.  cmdName gives the
'\"	option's name as specified in the class command, dbName gives
'\"	the option's name in the option database, and dbClass gives
'\"	the option's class in the option database.
'\"
'\" .UL arg1 arg2

.SH NAME
llength \- Count the number of elements in a list
.SH SYNOPSIS
\fBllength \fIlist\fR
.BE

.SH DESCRIPTION
.PP
Treats \fIlist\fR as a list and returns a decimal string giving
the number of elements in it.

.SH EXAMPLES
The result is the number of elements:
.CS
% \fBllength\fR {a b c d e}
5
% \fBllength\fR {a b c}
3
% \fBllength\fR {}
0
.CE
.PP
Elements are not guaranteed to be exactly words in a dictionary sense
of course, especially when quoting is used:
.CS
% \fBllength\fR {a b {c d} e}
4
% \fBllength\fR {a b { } c d e}
6
.CE
.PP
An empty list is not necessarily an empty string:
.CS
% set var { }; puts "[string length $var],[\fBllength\fR $var]"
1,0
.CE
