NAME    [Toc]    [Back]

     append - Append to	variable

SYNOPSIS    [Toc]    [Back]

     append varName ?value value value ...?

DESCRIPTION    [Toc]    [Back]

     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.
