break(n)		     Tcl Built-In Commands		      break(n)

______________________________________________________________________________

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"
	      }
