lreplace - Replace elements in a list with new elements
<H3><A NAME="M3">SYNOPSIS</A></H3>
<B>lreplace </B><I>list first last </I>?<I>element element ...</I>?<BR>
<H3><A NAME="M4">DESCRIPTION</A></H3>
<B>lreplace</B> returns a new list formed by replacing one or more elements of
<I>list</I> with the <I>element</I> arguments.
<I>first</I> and <I>last</I> specify the first and last index of the
range of elements to replace. 0 refers to the first element of the
list, and <B>end</B> (or any abbreviation of it) may be used to refer
to the last element of the list. If <I>list</I> is empty, then
<I>first</I> and <I>last</I> are ignored.
If <I>first</I> is less than zero, it is considered to refer to the
first element of the list. For non-empty lists, the element indicated
by <I>first</I> must exist.
If <I>last</I> is less than zero but greater than <I>first</I>, then any
specified elements will be prepended to the list. If <I>last</I> is
less than <I>first</I> then no elements are deleted; the new elements
are simply inserted before <I>first</I>.
The <I>element</I> arguments specify zero or more new arguments to
be added to the list in place of those that were deleted.
Each <I>element</I> argument will become a separate element of
the list. If no <I>element</I> arguments are specified, then the elements
between <I>first</I> and <I>last</I> are simply deleted. If <I>list</I>
is empty, any <I>element</I> arguments are added to the end of the list.
