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 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"
}
