What bug, please? According to BP, the "else" of a case doesn't require
"begin" and "end" for multiple statements, and that's how GPC behaves.

I think it is OK, since the "else" part is always terminated by the
"case"'s "end", so it's clear how far the else extends, even without
another "begin" and "end". SP and EP (AFAIK) don't use "else" but
"otherwise" in a "case" statement, so they don't apply here.
(If GPC behaves wrong with "otherwise", that's another thing, I don't know.)

Or do you mean anything different? (I was guessing the above from your
indentation since you didn't state the problem.)
