Using Ms-Dos With Your Apex; Introducing Ms-Dos - Epson Apex User Manual

Chapter 3

Using MS-DOS with Your Apex

In this chapter, you'll learn the basics of using MS-DOS with
your Apex. The MS-DOS operating system manages the routine
work of your system, such as keeping the computer's memory
organized, controlling the monitor display, accepting keyboard
input, and directing external communication.

Introducing MS-DOS

Your application software cannot communicate with your Apex
hardware without instructions from MS-DOS. The operating
system controls the system input and output, and the operation
of all disk drives.
Before you can use an MS-DOS application program, MS-DOS
must be running in the computer's memory. This means you
must first load MS-DOS so that the operating system can accept
your instructions and make the right connections.
To communicate with the operating system, you need to enter
MS-DOS commands. How much you need to know about the
MS-DOS commands depends on how you plan to use your
Apex. If you plan to use it only for running application pro-
grams, the few MS-DOS commands you need are introduced in
this chapter. If you plan to use advanced features or create your
own programs, you'll want to know as much as possible about
MS-DOS. See your MS-DOS reference manual.
