>>on of the properties for a Table object is PRIMERYKEY<<

Yes, it follows binary digit # 23 & is ASCII 20. If you
remove the last 8 binary digits you remove the Primary key
& it becomes candidate.

Do you know the layout of the binary coding? I see a
property sheet but the exact binary sequence baffles me.

Example: In a char field char # 1 in field 1 is 14
field 2 char 1 is 22
field 3 char 1 is 19

(all ASCII)

The question is since they are all character fields
why does the first ASCII char change???
