tcl7.6 User Commands - append






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.
