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 argu-
       ments.  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  exam-
       ple,  ``append  a $b'' is much more efficient than ``set a
       $a$b'' if $a is long.
