Interbase (also known as Starbase from Cognos) has extended the basic
blob type to allow user defined blob types and filters . The filters can
be written in a  3gl. Other basic blob operators include for loops,
blob load and dump (to external files) blob edit and c style getb,putb 
calls . The Interbase Gdml language which supports blobs allows you to
incorporate blob handling into Sql programs : blobs are also part of
the transaction control . 
 
Preprocessor support exists for Ada , Basic , C , Cobol , Fortan ,
Pascal and Pl/I . 

I would interested to hear about what people use blob type structures
for beyond holding just lots of text .
