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 does not 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 SEE ALSO
list(n), lindex(n), linsert(n), llength(n), lset(n), lsort(n), lrange(n) KEYWORDS
