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
