This product is already = = Interesting but I wonder what XDOS does about vector tables in the data = segment since Intel and Motorola store longwords differently ie. reversed. = And then there is always the clowns who pervert the idea by putting data in = the code segment. Yes, it has to maintain some data in the original Intel byte order. There is a performance hit, but it shouldn't be that difficult a programming task. As to data in the code segment, this must be detected and accounted for. It works. -- Dale Farnsworth 602-438-3092 uunet!unisoft!nud!df
