Hello I hope you are all well. I have IDs, such AB124008 in which AB = site of enrollment, 12, represents MD id, and 40008 represents the actual patient id in the study. I looked through all of Cody's books, or most, and know that I probably am missing something. They are all character / text variables. How do I separate all the IDs into: 1) site of enrollment - want it to be a text var 2) physician code - want to it to be a number 3) actual id - want to be a number Thanks! I have many enrolled patients in the study. I know there has to be an array to separate them.
