You don't get what's really happening. Firebird API (read: fbclient) 
represents every field with two parts: NULL indicator and field data. 
Ideally, nobody never should access the field data before checking the 
NULL indicator. It simply makes no sense. For NULL-indicated fields, 
there may be zeros, there may be garbage, there may be data of the 
previous record, or whatever.
