append(n) Tcl Built-In Commands append(n)
append - Append to variable
append varName ?value value value ...?
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

lappend - Append list elements onto a variable
lappend varName ?value value value ...?
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 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.
Using lappend to build up a list of numbers.
% set var 1
% lappend var 2
% lappend var 3 4 5
1 2 3 4 5
