To the other person who said "I'd like to see the value be *LOVAL or 
something"  I don't think that the same value in all data types would
accomplish it.  Lets say the value for Null was X'00'  how would that 
look in a Binary field?  I don't think it would "Special" I think it 
would be seen as just a normal Zero value, Right?   
I mean in a Zoned Decimal or a Alpha field it would stand out like a 
sore thumb on a DSPPFM  etc.  But the binary wouldn't look abnormal.
I think it's an attribute of a field myself. 
Maybe I'm wrong on this though.
