Tcl Built-In Commands
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.
KEYWORDS
