In turn, these procedures may call print_ref recursively if the data types that they handle contain one or more references. Whenever a reference is encountered, it is also checked with a hash %already_seen to determine whether the reference has been printed before. This prevents the routine from going into an infinite loop in the presence of circular references. All functions manipulate the global variable $level and call print_indented, which appropriately indents and prints the string given to it.
For example, if you had procedures such as create_matrix( ), get_element(mat,i,j), and set_element(mat,i,j), other procedures do not have to know the internal representation. Coding for change is often better than coding for run-time efficiency. We'll discuss this approach a great deal more in Chapter 7. 3 Professors, Students, Courses This example shows how you might represent professor, student, and course data as hierarchical records and how to link them up.
