Thanks! Bear with me, I am new to sas: I did see this on another thread: 1. how to convert char var to sas date? Hai.kuo Well, it seems working for me, please see: data have; infile cards; informat date $80.; input date ; cards; 05/21/2010 07/01/2010 03/01/2011 ; data want; set have; format _date mmddyy10.; _date=input(trim(date),MMDDYY10.); run; proc print;run; My suspicion is that you can't just convert char to numeric under the SAME variable name. You have to create another variable to the job, and if you want your old name back, you can always do it using date step options like: drop= rename=. However, without seeing your code and log, I can be totally off on this one. Regards, Haikuo However my problem is my date, year, and month are each a different variable, it is not together as in the example above. In the link you gave me, it seems to require the user to input the date manually. Thanks!
