Server Utilities :: Assign Numeric Value Generated From Sequence In Control File?

I have a control file like following:

LOAD DATA
INFILE *
INTO TABLE member
REPLACE
FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '"'
(
control_id,
name,
address
)

problem is that control_id value is not in data file and I have to assign to each row the same value generated from sequence or from unix variable.

For example, after I run sqlldr, I have to have records in the table like following:

control_id name address
---------- ---- -------
1847 Charlie 250 yonge st
1847 Peter 5 Brookbanks dr
1847 Ben 123 King st
.
.
.

How do I do that?
