NAME
       break - Abort looping command

SYNOPSIS
       break
______________________________________________________________________________

DESCRIPTION
       This  command is typically invoked inside the body of a looping command
       such as for or foreach or while.  It returns  a  3  (TCL_BREAK)  result
       code,  which  causes  a break exception to occur.  The exception causes
       the current script to be aborted out to the innermost  containing  loop
       command,  which  then aborts its execution and returns normally.  Break
       exceptions are also handled in a few  other  situations,  such  as  the
       catch  command,  Tk event bindings, and the outermost scripts of proce-
       dure bodies.

EXAMPLE
       Print a line for each of the integers from 0 to 5:

              for {set x 0} {$x<10} {incr x} {
                  if {$x > 5} {
                      break
                  }
                  puts "x is $x"
              }
