I dont find a mention in the RPG reference manual. > Well, it's not by explicit intent of RPG. We don't generate any special code to get this behaviour. I don't know if that makes it a bug though. It may be that pointer arithmetic is done just on the 16-byte variable itself, without the check for pointerness, for performance reasons, leaving the pointer-check for later when the pointer is dereferenced. Of course, the RPG compiler -could- do a check for a null-pointer and issue an exception, but we would have to think twice and three times about breaking compatibility before we did that. (I think it's very unlikely that we would change this behaviour.)
