Hello, Could you please post the exact message you got from the compiler?
I got mysefl problems with such convertions trying to compile FD-KEYB with FPC, but although I posted for help in the forums, I didn't get anything really useful and finally gave up. But I am curious if you get the same error. There's a compatibility mode that makes you switch between using @ or not before the procedure address, but in either case I got different compile time errors that made it unable for me to continue.
