Epson Apex, Руководство пользователя, Страница: 37 / 158

That’s because Epson changed the prompt by adding a command
in a file named AUTOEXEC.BAT. This file contains a series of
commands that your computer automatically runs when you
turn it on. One of these commands is PROMPT $P $G, which
modifies the prompt to display your directory location on the
disk. For simplicity, all of the examples in this manual show the
default command prompt,
A>
or
C>.
For more information about the AUTOEXEC.BAT file, see
“Using an AUTOEXEC.BAT file” in Chapter 3, or see your
MS-DOS reference manual.
Before you continue, make a working copy of the diskette
containing the MS-DOS operating system and the diskette
containing GW-BASIC; then store the originals safely away.

Copying System Diskettes
Follow the steps below to make copies of your two system
diskettes. Use these working copies for daily use and store the
originals in a safe place.
The procedure for copying a diskette differs slightly depending
on whether you have an Apex Plus or an Apex Plus 20. Follow
the procedure below that applies to your system. In either case,
you will need two blank 5 1/4-inch, 360 KB double-sided,
double-density diskettes. Make sure the system diskettes are
write-protected to prevent accidental erasure (see “Write-
protecting diskettes” in Chapter 2).

1. The
A>
prompt should be displayed on the screen. If it
is not, follow the steps in the previous section, “Loading
MS-DOS on the Apex Plus.”
