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.
