Nope, that's correct. Take a look at the syntax diagram for case statement
here:
http://www.freepascal.org/docs-html/ref/refsu50.html
As you can see, each "case" is terminated by ";". From the parser point of
view, your code is exactly parsed as:
No, that shows a semicolon separating successive cases, not terminating
each one. What's more statement can be a compound statement and
that's similarly defined as using ; as a separator.
Bit of an old chestnut, and my recollection is that an extra semicolon
would crash some versions of Turbo Pascal. I'm not sure where my copy of
J&W is, so I can't go back to the BNF... but it wouldn't help since
else was added to the case statement by Turbo Pascal which explicitly has
case expression of case-element { ; case-element } else
where a case-element ends with a statement which can be a
compound-statement which again defines ; as a separator.
(Oh Lord this is all we need: a syntax war to round off the year.)
