Examples

The following examples of execution while loop, less than 20 output a value in a variable, and a greater than 15 terminates execution cycle:

--[ 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 above code is executed 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
