NAME
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. 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.
