System
MS-DOS “ Microsoft Disk
Operating System” is an
operating system designed for
8086/8088 based computers.
Through MS-DOS an operator
can keep track of files, run and
link programs, and access
peripheral devices (ie. printers
and disk drives) that are
attached to your computer.
The operating system MS-DOS
from Microsoft, together with
CP/M-86 stands to become the
standard 16 bit operating
system. Both operating systems
are very similar as can be seen
by the system commands and
internal structure. The only
difference is MS-DOS is faster
than CP/M-86 due to enchanced
disk handling features. It is easy
to use because it tolerates a
great many user errors and
gives the user detailed error
messages.
Using the Command
Programs
Command programs are loaded
automatically under MS-DOS
with the system diskette. There
are two types of MS-DOS
commands: Internal commands
and External commands.
Internal commands are the
simplest, most commonly used
commands. You cannot see
these commands when you do a
directory listing on your MS-DOS
disk, they are part of the
command processor. When you
type these commands, they
execute immediately.
External commands reside on
diskettes as program files. They
must be read from disk before
they can execute. If the diskette
containing the command is not
in the drive, MS-DOS will not be
able to find and execute the
command.
This section describes nine (9)
of the command programs you
will need most often. We have
written a section for each of
these command programs.
• Check the system directory
• Format a new diskette
• Make a copy of that diskette
• Delete a file/files
• Check disk for consistency
and errors
• Update the system
• Recover a file(s) or diskette
• Print while processing other
MS-DOS files
• Software conversion
The description that follows
assumes that the blank diskettes
available for use have not yet
been initialized (formatted) to
the format of the OLYMPIA
PEOPLE
Personal Microcomputer.
This means that you must first
format the blank diskette provided
before data can be stored or a
copy procedure started.
This is true for blank diskettes
that you are using for the first
time. (See page 5/15).
NOTE:
When inputting the following
command sequences, type in all
characters and spaces
exactly
as they appear in the examples.
Even when correct spelling
would require spaces, they must
be omitted here.
