Chris,
You aren't going to find any such documentation on the binary content memos. Why can't you use an ALTER TABLE command to drop the PK?
>I'm looking for some documentation on the structure of the properties field in a DBC file. MS provides some limited documentation in the FILESPEC directory on a standard installation, but it does not provide much info. It references "codes" in the property field, and I can examine the binary data in the property field and match up some of the codes, but documentation would be very helpful.
