       lappend - Append list elements onto a variable

       lappend varName ?value value value ...?

       This  command treats the variable given by varName as a list and appends each of the value
       arguments to that list as a separate element, with spaces between  elements.   If  varName
       doesn't	exist,	it is created as a list with elements given by the value arguments.  Lap-
       pend is similar to append except that the values are appended as list elements rather than
       raw  text.  This command provides a relatively efficient way to build up large lists.  For
       example, ``lappend a $b'' is much more efficient than ``set a [concat $a [list $b]]'' when
       $a is long.
