OK, but version numbers tell me nothing. What I am looking for is an
explanation of how Firebird (the package) can tell which bytes belong to
which fields. Somehow Firebird must be able to tell the difference between
the following two records:
FirstName LastName
'Jim' 'Starkey'
'Jim Starkey' ''
It may well be that it was coded in the Interbase days and has not been
looked up until now. Or maybe it's the blob in the "RDB$DESCRIPTOR" field,
in which case I do not know how to decode it into text.
