NAME
       lappend - Append list elements onto a variable

SYNOPSIS
       llaappppeenndd 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.  LLaappppeenndd is similar to
       aappppeenndd 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, ``llaappppeenndd aa $$bb'' is much more efficient than
       ``sseett aa [[ccoonnccaatt $$aa [[lliisstt $$bb]]]]'' when $$aa is long.
