Semantics

boolean_expression

The first boolean_expression is always evaluated. Except for the first one, a boolean_expression is evaluated only if the values of the preceding expressions are FALSE.

If a boolean_expression is evaluated and its value is TRUE, the statements after the corresponding THEN run. The succeeding expressions are not evaluated, and the statements associated with them do not run.

ELSE

If no boolean_expression has the value TRUE, the statements after ELSE run.
