Hello SAS Users,   I'm relatively new to SAS so I'm looking for some advice on how to compare values between certain variables. I have a sample dataset  (named Test) that looks like this:   Test PersonID A1 A2 B1 B2 1 TRUE FALSE TRUE FALSE 2 FALSE TRUE FALSE TRUE 3 TRUE FALSE TRUE TRUE 4 TRUE FALSE FALSE FALSE 5 FALSE TRUE FALSE TRUE   I am needing to compare A1 to B1, followed by A2 to B2. What I want is to look and see if there is a least one "TRUE" between them and then create new variables for each comparison ("New_A", "New_B") that indicates at least one of the variables contains "TRUE". The new dataset (named Test2) I want to create will look something like this:    Test2 PersonID A1 A2 B1 B2 New_A New_B 1 TRUE FALSE TRUE FALSE yes no 2 FALSE TRUE FALSE TRUE no yes 3 TRUE FALSE TRUE TRUE yes yes 4 TRUE FALSE FALSE FALSE yes no 5 FALSE TRUE FALSE TRUE no yes   I already have written code that does this (the example below just shows for New_A but it works for New_B also): data test2; set test; if A1 = "TRUE" and B1 = "TRUE" then New_A = "yes"; else if A1 = "TRUE" or B1 = "TRUE" then New_A = "yes"; else New_A = "no"; run; The problem I'm running into is that in the actual dataset that I will eventually have to use, there is about 150 comparisons that I will have to do and I'm not really wanting to type them all out with "if-then-else" statements. I'm not too familiar with arrays or macros yet but I was wondering if they might make this process more efficient for me. Would anyone know of a faster way that I could do these comparisons? Any help/advice would be great!    P.S. I am using SAS EG 7.1       ... View more
