Exactly right, but in context appending extra semicolons after
control structure statements is a common beginner's error with
potentially problematic ramifications.
Consider:
if (Condition1) then;
DoSomething;
or
while (Condition2) do;
DoSomethingElse;
I've seen newbies banging their heads over why DoSomething is
called no matter what Condition1 evaluates to or why
DoSomethingElse is called only once, regardless of Condition2.
