- 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.
