append - Append to variable
SYNOPSIS
append varName ?value value value ...?
_________________________________________________________________DESCRIPTION
Append all of the value arguments to the current value of variable varName. If varName doesn't exist, it is given a value equal to the
concatenation of all the value arguments. The result of this command is the new value stored in variable varName. This command provides
an efficient way to build up long variables incrementally. For example, ``append a $b'' is much more efficient than ``set a $a$b'' if $a
is long.
EXAMPLE
Building a string of comma-separated numbers piecemeal using a loop.
set var 0
for {set i 1} {$i<=10} {incr i} {
append var "," $i
}
puts $var
# Prints 0,1,2,3,4,5,6,7,8,9,10

lappend(3tcl) Tcl Built-In Commands lappend(3tcl)__________________________________________________________________________________________________________________________________________________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
