That can't explain a "EAccessViolation: Access violation". It could be a
syntax error, yes, but never an exception. And it happens before the
code part.

Description

EAccessViolation is raised when the OS reports an Access Violation, i.e.
when invalid memory is accessed.

Yes, I'll do that.

Actually, the OpenC2Pas program did a lot of that :-)

Hopefully, one program translates most of the declarations, and another
a good part of the code :-)
