lindex - Retrieve an element from a list
<H3><A NAME="M3">SYNOPSIS</A></H3>
<B>lindex </B><I>list index</I><BR>
<H3><A NAME="M4">DESCRIPTION</A></H3>
This command treats <I>list</I> as a Tcl list and returns the
<I>index</I>'th element from it (0 refers to the first element of the list).
In extracting the element, <I>lindex</I> 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 <I>index</I> is negative or greater than or equal to the number
of elements in <I>value</I>, then an empty
string is returned.
If <I>index</I> has the value <B>end</B>, it refers to the last element
in the list, and <B>end-</B><I>integer</I> refers to the last element in
the list minus the specified integer offset.
