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
    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"
}
