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.
