Command
Function
This useful command allows you to display the contents of an
ASCII (text) file on the console screen. The
TYPE
command can
be used with options which enable or disable paged mode
displays. The
<PAUSE>
key or
<CTRL-S>
combination may be
used to halt the display. You can press any key or use the
<CTRL-Q>
combination respectively to restart.
<CTRL-C>
may be
used to abort the execution of the
TYPE
command and exit to the
system.
Examples:
TYPE C
\
:AUTOEXEC.BAT
will display the contents of the AUTOEXEC.BAT file stored in
the root directory of drive C:. The file will be sent to the screen.
TYPE B
\
:PROG1.ASM
will display the contents of a file called PROG1.ASM stored in
the root directory of the disk in drive B. The file will be sent to
the screen.
TYPE C:
\
WORK
\
*.DOC
will display the contents of
all
the files with a DOC extension
present in the WORK directory of the hard disk (drive C:).
You can use the
TYPE
command to send the contents of a file
to the printer at the same time as viewing it on the screen. If you
need to do this, press
<CTRL-P>
before you issue the
TYPE
command (but do make sure that the printer is 'online' and ready
to go!). To disable the printer output you can use the
<CTRL-P>
combination a second time.
The ability to redirect data is an extremely useful facility. DOS
uses the
<
and
>
characters in conjunction with certain
commands to redirect files. As an example:
TYPE A:
\
README.DOC >PRN
will redirect normal screen output produced by the
TYPE
command to the printer. This is usually more satisfactory than
using the
<PRT.SCREEN>
key.
TYPE
The
VER
command displays the current DOS version.
VER
The
VERIFY
command can be used to enable or disable disk file
verification.
VERIFY ON
enables verification whilst VERIFY OFF
disables verification. If
VERIFY
is used without
ON
or
OFF
, the
system will display the state of verification (either 'on' or 'off ').

The
VOL
command may be used to display the volume label of
a disk.

Unlike internal commands, these commands will not function unless the appro-
priate DOS utility program is resident in the current (default) directory. External
