06 — If: make a choice

Programs choose. if runs one set of lines when a condition is true, and else runs another when it is not.

#Steps

1. Create choose.nme:

   set ready to True
   if ready
       show Go
   

   copyrun it →

   The line under if is indented. Because ready is True, it prints Go.

2. A whole condition fits on one line with then:

   if score is greater than 10 then show You won
   

   copyrun it →

   Korean puts the condition ending on the comparison:

   만약에 점수가 10보다 크면 성공 말해줘
   

   copyrun it →

3. Choices with else need a block. The flat form closes with end:

   set score to 1
   if score equals 1
   show one
   else if score equals 2
   show two
   else
   show other
   end
   

   copyrun it →

   The Korean block uses 아니면 만약에 and 아니면 and closes with 끝.

#Try it yourself

Welcome a guest only when a name exists:

set name to Mina
if name exists
    show Welcome name
end

#What you learned

• if condition with an indented line runs it when the condition is true.
• if ... then show ... is a one-line condition; 만약에 ...면 is Korean.
• else / 아니면 and else if / 아니면 만약에 add other choices.
