Your code needs a cards; statement after the end; and before the data.
Your syntax is wrong in select, it should be (here is one example, you can change the rest of them):
when (CourseGrade ge 93 and CourseGrade le 97) FGrade = 'A';
Also, your select statements will assign a 93 to A-, even though you appear to have it in the A category, because your conditions in the select statement overlap, and you probably want to fix that.
For your future benefit, when you get errors in the log, SHOW US THE LOG. Show us the entire log of the step where the errors are, in the sequence it appears in the log, with nothing chopped out.
