9.7. SORTINT: Sorting Integers from a File

As a second example of working with files, we present a companion to the SORTSTR program, which performed a bubble sort on strings entered interactively. The SORTINT program (Figure 9-6) reads integer quantities from an ASCII text file into internal binary storage as quad words, sorts them using the bubble sort algorithm, and writes the ordered list of signed integers to a new text file, one per line. This program utilizes I/O features of the SCANFILE program to implement the bubble algorithm of the SORTSTR program.
