Module: Loop statement with condition - while

 sum=0
 input x // enter the first number
 while x != 0 // the input end sign is set in the condition,
 nc // that is, until you enter zero
   sum = sum + x // you can do something with the original number.
                  // You can add a number check for some condition, etc.
   input x // enter the next number
 kts
 print sum //result output
