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"
}
