Pointers and tagged values are merged, using the assumption that the high bit isn't used for a valid address (untrue on some machines). This assumption isn't hard to remove. (I don't have the source anymore -- not my job -- and it's been 3 years, so I can't tell you where to look other than that it is in one of the main header files. I also recall having to fix some place where 0 was considered a valid DB reference.) Questions to: Karen Morrissey AT&T Bell Labs 303-538-4587 att!druhi!kam
