NAME
       lappend - Append list elements onto a variable

SYNOPSIS
       lappend varName ?value value value ...?
_________________________________________________________________

DESCRIPTION
       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.   Lappend	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.

EXAMPLE
       Using lappend to build up a list of numbers.
	      % set var 1
	      1
	      % lappend var 2
	      1 2
	      % lappend var 3 4 5
	      1 2 3 4 5
