<H3><A NAME="M4">DESCRIPTION</A></H3>
|
|
This command treats each argument as a list and concatenates them
|
|
into a single list.
|
|
It also eliminates leading and trailing spaces in the <I>arg</I>'s
|
|
and adds a single separator space between <I>arg</I>'s.
|
|
It permits any number of arguments. For example,
|
|
the command
|
|
<PRE><B>concat a b {c d e} {f {g h}}</B></PRE>
|
|
will return
|
|
<PRE><B>a b c d e f {g h}</B></PRE>
|
|
as its result.
|
|
<P>
|
|
If no <I>arg</I>s are supplied, the result is an empty string.
