SELECT CASE construct

＜Syntax＞

select-case-stmt
[ case-stmt
block ]...
end-select-stmt

＜Semantics＞

The SELECT CASE construct begins with a SELECT CASE statement and ends with an END SELECT statement. When the SELECT CASE statement is executed, its selector expression is evaluated; if its value satisfies one of the CASE conditions, the corresponding block is executed, otherwise control is transferred to the END SELECT statement.

Note that the CASE conditions must be mutually exclusive (so that no more than one condition can be satisfied at a time).
