Hello, I am trying to filter a health data to identify my study population using specific Drug Identification Numbers (DINs) for asthma inhaler medications. I have a list of DINs I am interested in. I will like SAS to identify individuals and observations that matches one of the DINs. Here are some of the DINs I am interested in: 812463; 824216, 851752;851760;851841 etc. I really need help on this. Any comments would be greatly appreciated. Thank you
