Data Flow: Converting Data In Multiple Columns

Hi,

I'm just wondering what's the best approach in Data Flow to convert the following input file format:

Date, Code1, Value1, Code2, Value2

1-Jan-2006, abc1, 20.00, xyz3, 35.00

2-Jan-2006, abc1, 30.00, xyz5, 6.30

into the following output format (to be loaded into a SQL DB):

Date, Code, Value

1-Jan-2006, abc1, 20.00

1-Jan-2006, xyz3, 35.00

2-Jan-2006, abc1, 30.00

2-Jan-2006, xyz5, 6.30

I'm quite new to SSIS, so, I would appreciate detailed steps if possible. Thanks.
