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
