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"
}
