.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

.SH "SEE ALSO"
list(n), lappend(n), lindex(n), linsert(n), lsearch(n), 
lset(n), lsort(n), lrange(n), lreplace(n)

.SH KEYWORDS
element, list, length
