If you use nested loops, the break statement will stop the execution of the innermost loop and start executing the outer loop statement.

Example

The following example executes a while loop, outputs the value of a when variable a is less than 20, and terminates the loop when a is greater than 15:

--[ 定义变量 --]
a = 10

--[ while 循环 --]
while( a < 20 )
do
   print("a 的值为:", a)
   a=a+1
   if( a > 15)
   then
      --[ 使用 break 语句终止循环 --]
      break
   end
end

The execution result of the above code is as follows:

a 的值为:    10
a 的值为:    11
a 的值为:    12
a 的值为:    13
a 的值为:    14
a 的值为:    15
