lappend(n) Tcl Built-In Commands lappend(n)
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, is much more efficient than 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
