SQL*Loader - two-digit year

Question

Hello,
Oracle 9
I'm loading data into a table using sql*loader. Included is a date field with a two-digit
year. When the data is loaded, the century for the date defaults to 20. Is there a way to
change the ctl file to set the century based on a pivot year. For example if the year
is greater than 50 then change the date so that the century is 19, otherwise the century would
be 20.
Here's data:
12345678901234567890123456789 <-- postion
0000000 <--- record 1
0010000062603DUNNING PATRI <--- record 2
0000000 <--- record 3 0010000073002BARRIS THEOD <--- record 4
0000000 <--- etc 0000000 0000000 0000000000000BANK PEOPL
Here's the ctl file:
LOAD DATA
INFILE 'S4_MST01.TST'
REPLACE
INTO TABLE mreadm.SBX_ACCOUNT_INFO
LAST_PAYMENT_AMOUNT POSITION(01:07) DECIMAL EXTERNAL ":LAST_PAYMENT_AMOUNT/100",
LAST_PAYMENT_DATE POSITION(08:13) DATE "MMDDYY" NULLIF (77:78) = '00',
CUSTOMER_SHORT_NAME POSITION(14:29) CHAR
Thanks.

There probably is a way to do it at the instant you load the data. I suggest you use a different approach.
Load the data into the table. Then execute a simple statement like:
select case when(to_number(to_char(sysdate,'YY'),99)) > 50 THEN '20' ELSE '00' END from dual;
replace the sysdate above by the name of your column and issue a simple update statement. Let me know if I confused you, I can give a more specific exmaple on updating.
