[firebird-support] PASCAL UDR - stored procedure BLOB param and return

['livius' liviusliv...@poczta.onet.pl [firebird-support]]

Hi,

i can work in udr with near to all types of params but
how can i work with blob as input parameter  and output parameter 
for stored procedure?

should this be as BLOB or something else? 

InMessage = record
        nr: Integer;
        nrNull: WordBool;
        dane: Blob;
        daneNull: WordBool;
    end;

InMessagePtr = ^InMessage;

OutMessage = record
        result: Integer;
        resultNull: WordBool;
        dane: Blob;
        daneNull: WordBool;
    end;

    OutMessagePtr = ^OutMessage;

how to consume this?

please advice
