33        CONTINUE
22     CONTINUE
       STOP
       END

6. (40 minutes, 38 points)

Write a simple FORTRAN 77 program to accept data in the following format:

Columns Description                                 Example

1-7             Student ID                                  9512345
11-35           Student Name                        St. Louis, Rejean
41-45           Total Course Assignments (100)    78
46-50           Mid Term also out of 100            67
51-55           Final exam out of 100               73

Your program should read a group of records with the above data, terminated by 9999999. For each input record, print the input data, under appropriate headings, and calculate and print the final course mark for each student, all on the same line. The course mark is calculated by counting the assignments for 30%, the midterm for 20%, and the final exam for 50%. The course mark should be printed to one decimal place for each student (e.g. 73.3 for the above example).

At the end of the class list, print the Student ID and Name of the TOP THREE students in the class.

Your program does NOT need to use 2-D arrays nor subprograms.

WRITE your program, with Control Lines, neatly:
