説明

Case 構造により、プログラマは複数の条件をテストするための構造を作成できます。

初の真の条件のみが実行され、他のすべての条件はスキップされます。

最後の条件としてオプションのelseがある場合、他の条件が満たされない場合はこれが実行されます。

Example

for t = 1 to 10
begin case
case t < 3
print t + " is less than 3"
case t < 7
print t + " is less than 7 but 3 or larger"
else
print t + " is 7 or larger"
end case
next t

displays:

1 is less than 3
2 is less than 3
3 is less than 7 but 3 or larger
4 is less than 7 but 3 or larger
5 is less than 7 but 3 or larger
6 is less than 7 but 3 or larger
7 is 7 or larger
8 is 7 or larger
9 is 7 or larger
10 is 7 or larger
