COMMAND: HELP DOCUMENTATION : On-line
FUNCTION: Provides an on-line description of all the commands and utilities
available on the system as well as brief descriptions of various
features of the system.
FORMAT: HELP [keyword]
TYPE: Public domain software (D.N. Ikle,1671 Newport,Denver,CO 80220)
REMARKS: keyword is the 1-8 character feature for which help is desired.
The optional keyword can be ?, to display a summary HELP screen, the
name of a DOS or other system command or utility, or the name of
certain system features. The first 8 non-blank characters after
HELP become the keyword. Entering the keyword HELP provides a
detailed description of the HELP facility and a list of the keywords
that describe certain system features. Entering the keyword
COMMANDS provides a list and brief description of all the commands
and utilities available on the system. Omitting the keyword on the
command line causes a menu to be displayed that prompts for entry of
a keyword. If an invalid keyword is entered the speaker beeps and
the HELP menu is displayed.
Following entry of a valid keyword, 1 to 8 screens of text are
displayed from the text file that describes the command, utility, or
feature. From any individual HELP screen, press Enter to return to
the HELP menu, or Escape to return to DOS. If Escape is pressed,
all but the first line of the current screen remains on the display
to allow the user to enter the command at the bottom of the display
while viewing most of the instructions. The cursor control keys Up,
Dn, PgUp, PgDn, Home and End can be used to move backward or forward
a line or a screen at a time or to display the first or last HELP
screen in the current file. These options are summarized on line 25
of the display, which also indicates whether the file is continued
on another screen or the end of file has been reached.
A notation indicates if a public domain utility has a document
file On-Line in \utility\doclib, Off-Line in a manual, or has no
documentation at all. HELP support files are in \help, and the HELP
screens for the system commands and utilities are in \help\pcdos,
\help\private, and \help\public.
The following keywords can be used to obtain descriptions of
various special features of the system:
ANSI
ANSI.SYS is a DOS installable device driver that provides
enhanced keyboard and display capabilities.
AUTOEXEC
An AUTOEXEC.BAT file in the root directory of the boot disk is
executed on system start-up. Commands installed therein are
executed immediately and initialize the system with whatever
features are included.
BATCH
Batch files have the extension .BAT and are executed from DOS. They
can contain special DOS sub-commands that control their execution,
regular DOS or public domain system commands, and elements of the
Extended Batch Language.
COMMANDS
This feature provides an alphabetic list of all commands available
on the system and a one line description of each.
CONFIG(uration)
Various configuration commands can be included in a CONFIG.SYS file
in the root directory of the boot disk. These commands define
system characteristics including the definition of installable
device drivers.
FILTERS
This advanced DOS 2.+ feature provides several commands that read
data from a standard input device, modify the data, and then write
the data to a standard output device.
NOTATION
This feature describes the notation used in the displays of the
On-Line HELP facility.
PIPES
This advanced DOS 2.+ feature allows the screen output of one
program to be used as the keyboard input of another program.
REDIRECT(ion)
This advanced DOS 2.+ feature allows a program to receive its
input from a source other than the keyboard or to direct its output
to a device other than the display screen.
SYSTEM
This feature describes the system enhancements that are defined in
the AUTOEXEC.BAT and CONFIG.SYS files at system start-up.
