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 TCL_BREAK 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 com-
       mand, Tk event bindings, and the outermost scripts of procedure 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"
	      }
