The IF construct selects a single block of statements for execution.
The conditions (expressions) in the IF THEN statement and the ELSE IF statements are evaluated in order until
one has the value true; if this is found, the block following that statement is executed.
If all the conditions are false, the ELSE block will be executed if present; with all conditions false and no ELSE block,
control will be transferred to the END IF statement.
