This is a valid part of a TurboPascal 5.0-program:

    CASE n OF
      1: p := 7;
      2: p := 6;
      3: IF x = 4 THEN
           p := 5;
         ELSE
           p := 4;
    END

What's wrong?

Well, I guess you spotted it. The ELSE is an ELSE in the CASE-
statement, and not in the IF-statement, as the indention suggests.
And the error is the semicolon at the end of "p := 5".

It bit me yesterday ... I would prefer if the CASE-ELSE had
been OTHERWISE.
