19. Assume you have a Pep/9-type computer and the following disk files:

› File A: A Pep/9 assembly language assembler written in machine language

› File B: A C-to-assembly-language compiler written in assembly language

› File C: A C program that will read numbers from a data file and print their median

› File D: A data file for the median program of file C To compute the median, you must make the four computer runs described schematically in FIGURE 5.29 . Each run involves an input file that will be operated on by a program to produce an output file. The output file produced by one run may be used either as the input file or as the program of a subsequent run. Describe the content of files E, F, G, and H, and label the empty blocks in Figure 5.29 with the appropriate file letter.
