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  ele
       ments given by the value arguments.  Lappend is similar to
       append except that the values are appended  as  list  ele
       ments rather than raw text.  This command provides a rela
       tively efficient way to build up large lists.   For  exam
       ple,  ``lappend a $b'' is much more efficient than ``set a
       [concat $a [list $b]]'' when $a is long.
