Tcl Built-In Commands                                  append(1T)



_________________________________________________________________

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.
     The  result of this command is the new value stored in vari-
     able varName.  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.

EXAMPLE
     Building a string of comma-separated numbers piecemeal using
     a loop.
          set var 0
          for {set i 1} {$i<=10} {incr i} {
             append var "," $i
          }
          puts $var
          # Prints 0,1,2,3,4,5,6,7,8,9,10
