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.  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.
