Dear Allstat I have a problem in doing SAS program. I have a data set contains many dates in form of MMDDYY8. some of these dates are in year 2000. When I try to make INPUT for these dates, it gives me negative values for year 2000 dates. my question is how I modify these date to give me the actual values of input option. are there any SAS command or option to do that. I am very thanks for your help. ___________________________________________ Khaled El-Sayed Hassan Demographer & Data Analyst (M.
