If <I>varName</I> doesn't exist, it is given a value equal to the concatenation of all the <I>value</I> arguments. This command provides an efficient way to build up long variables incrementally. For example, ``<B>append a $b</B>'' is much more efficient than ``<B>set a $a$b</B>'' if <B>$a</B> is long. <H3><A NAME="M5">SEE ALSO</A></H3> <B><A HREF="../TkCmd/concat.htm">concat</A></B>, <B><A HREF="../TkCmd/lappend.htm">lappend</A></B> <H3><A NAME="M6">KEYWORDS</A></H3> <A href="../Keywords/A.htm#append">append</A>, <A href="../Keywords/V.htm#variable">variable</A> <HR><PRE> <A HREF="../copyright.htm">Copyright</A> © 1993 The Regents of the University of California. <A HREF="../copyright.htm">Copyright</A> © 1994-1996 Sun Microsystems, Inc. <A HREF="../copyright.htm">Copyright</A> © 1995-1997 Roger E.
