VARCHAR FOR BIT DATA and INSERT

[Samuel Meder]

I'm at a loss for how to actually drive a insert of a row that  
contains a value of type VARCHAR FOR BIT DATA. Things I have tried so  
far:

INSERT INTO table VALUES ('my bitstring')
INSERT INTO table VALUES (my bitstring)
INSERT INTO table VALUES (X'my bitstring')
and various combinations with CAST. No of these work, so does anyone  
have an example of how to actually do this?
