lappend(TCL)


lappend -- append list elements onto a variable

Syntax

lappend varName [value value value ...]

Description

This command treats the variable given by varName as a list and appends each value argument 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.
