Just what date is 10622 supposed to be?
If that is a SAS date value as implied by your code that would be 01/30/1989 and you would use the format MMDDYY10.
Formats display. Informats read.
If that is not the expected result for 10622 then you need to provide some details, such as what your RAW data from the CSV looks like. Hint: DO NOT open the CSV in a spreadsheet. Open the CSV file with a text editor like Notepad, copy a few lines of the data and then paste the copied lines into a code box opened on the forum with the </> to preserve actual format of your data. The main message windows will reformat text.
Since you have some sensitive data XXXX out the SSN values.
