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"
}
