Isn't that the point of null?

>Will a GUID ever be ebcdic or ascii blanks?
Doubtful, given that the "spatially unique value is specified as an IEEE 802
address." In english, the last 6 bytes of the GUID come from your ethernet
card unless your card's MAC address is 404040404040 or 202020202020 you
won't see blanks in a GUID. Of course, even if your MAC address is 40's or
20's you probably still won't see a blank bacause of the format of the
higher-order bytes.

Will a GUID ever be ebcdic or ascii blanks?

So can a program check the 16 byte guid field for blanks to know that a guid
has not yet been assigned?

thanks,
