Little known fact (because, seriously, how would you know) , I write a lot of code while sitting on a plane and I can’t always connect to the Internet. NOT ALL QUOTATION MARKS ARE CREATED EQUAL Sometimes, when I copy and paste my code into SAS Studio, it doesn’t work. if compress(q23) = “3/4” then…
