07 — While: keep going

repeat runs a fixed number of times. while keeps running as long as a condition stays true — and stops when it becomes false.

#Steps

1. Create count.nme:

   set score to 0
   while score is less than 3
   show score
   add 1 to score
   end
   

   copyrun it →

   The block closes with end, so indentation is optional. The program prints 0, 1, 2 and stops when score reaches 3.

2. Korean uses 동안 and 끝:

   점수는 0
   점수가 3보다 작은 동안
       점수 보여줘
       점수에 1 더해
   끝
   

   copyrun it →

3. English and Korean can mix in one condition. The Korean ending 동안 follows the subject:

   점수는 0
   while 점수가 3보다 작을 동안
   show 점수
   add 1 to 점수
   end
   

   copyrun it →

4. A spoken one-line loop puts the ending on the subject:

   준비는 참
   준비하는동안 성공 말해줘
   준비는 거짓
   

   copyrun it →

   The last line makes the condition false, so the loop stops after one round. Without it the loop never ends.

#Try it yourself

Loop while a name is missing, asking until one appears:

set name to empty
while name equals empty
    ask name What is your name?
end

#What you learned

• while condition ... end loops while the condition is true.
• 동안 조건 ... 끝 is the Korean spelling.
• The loop must change its condition, or it never stops.
• Spoken Korean can end the loop on the subject: 준비하는동안.
