Chapter 11 Input and Output

This chapter covers three broad topics: keyboard and screen input/output (I/O), reading and writing standard disk files, and low-level disk access. It also introduces several common string-handling functions.

The information in this chapter is mostly related to input/output for character-based DOS and QuickWin programs. For information about Windows input/output, see “Creating Windows Programs” on page 223.

WARNING:

QuickWin programs can only run in Windows Standard or Enhanced mode. Do not run a QuickWin program in Real mode.
