87 — Screen: clearing, ruling and boxing

Output piles up and the screen gets messy. Four sentences tidy it.

#Steps

1. Make screen.nme:

   clear the screen
   

   copyrun it →

   Everything printed before it disappears. Korean is 화면 지워.

2. Rule a line to separate one part from the next:

   draw a line
   

   copyrun it →

   Korean is 줄 그어.

3. A centred line looks like a title:

   say in the middle Today's menu
   

   copyrun it →

   Korean is 가운데 말해줘 오늘의 차림표.

4. Put a box around anything that has to be noticed:

   say in a box Three minutes left
   

   copyrun it →

   Korean is 상자로 말해줘 남은 시간은 3분입니다. A Korean letter takes two columns in a terminal, and the box counts that width so it never comes out crooked.

5. Together they make one screen:

   clear the screen
   draw a line
   say in the middle Today's menu
   draw a line
   say in a box Coffee, tea, water
   

   copyrun it →

#Try it

Combine it with a question, and redraw the screen after the answer:

clear the screen
say in the middle Tell me your name
draw a line
ask name Your name
clear the screen
say in a box Nice to meet you
say in the middle name

#What you learned

• clear the screen / 화면 지워 empties the screen.
• draw a line / 줄 그어 rules one horizontal line.
• say in the middle … / 가운데 말해줘 … centres a line.
• say in a box … / 상자로 말해줘 … draws a box around it.
• Both the box and the centring count Korean letters as two columns wide.
