SYNOPSISappend 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 argu-
ments. 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.
