Calculating AGE in completed in SAS

Question

I have a date of birth variable in my dataset, however, the reference date 2FEB2022 is not in the dataset and I would like to calculate age. How do you calculate age in completed years?

Answer 1

它会是这样的，虽然我面前没有 SAS 来测试，所以我的语法可能有点错误：

AGE=INTCK('YEAR',DateOfBirth,'02FEB2022'd,'C');
