trying to debug pseudocode

Question

2. Th e Springwater Township School District has two high
schools—Jeff erson and Audubon. Each school maintains a
student fi le with fi elds containing student ID, last name, fi rst
name, and address. Each fi le is in student ID number order.
Design the logic for a program that merges the two fi les
into one fi le containing a list of all students in the district,
maintaining student ID number order.

Answer 1

Well, beside the fact that the there's no indication of reading or writing anywhere...

The program's goal is to sort-merge two files into one, yet the program opens only one input file (and one output file). The program cannot accomplish the goal; it will not do what it's supposed to do.
