.SH NAME
|
|
lindex \- Retrieve an element from a list
|
|
.SH SYNOPSIS
|
|
\fBlindex \fIlist index\fR
|
|
.BE
|
|
|
|
.SH DESCRIPTION
|
|
.PP
|
|
This command treats \fIlist\fR as a Tcl list and returns the
|
|
\fIindex\fR'th element from it (0 refers to the first element of the list).
|
|
In extracting the element, \fIlindex\fR observes the same rules
|
|
concerning braces and quotes and backslashes as the Tcl command
|
|
interpreter; however, variable
|
|
substitution and command substitution do not occur.
|
|
If \fIindex\fR is negative or greater than or equal to the number
|
|
of elements in \fIvalue\fR, then an empty
|
|
string is returned.
|
|
|
