Write a FORTRAN 77 program that reads 20 records, each record containing a student's name and final score for a course. In each record, the name is in columns 1-17 and the score is an integer in columns 21 - 22.

- Print out each student's name, mark, and the message 'PASSED' if the score is greater than 65, or 'FAILED' if the score is less than or equal to 65.
- Find and print the best student's name and mark. (Assuming that there is only ONE top student).
- Find out and print how many students passed the course, and how many failed it.
- Show the control lines used to run your program.
