If you want to create a new varable based on NUM_credits you might want to use log(Num_credits +1) not X. I suspect you do not have a variable X before the transform. Your output shows X with missing values because you references a variable X, so SAS needed to create the variable with missing values. And since X was missing then the result was missing.
