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.
