I am using PROC IMPORT to read in a .csv file. I have a variable PATIENT that is a patient ID number. My issue is that most of the entries are numbers, but the very last one has an "S" before it suggesting that this patient was screened from the study. SAS hits that last record thinking that it should be a number, deletes it, and gives me an error message saying that import was unsuccessful. Is there an option that I am not finding that will adjust the variable type if there are characters in a variable?
