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
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
value
s 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.
