	1.  INTRODUCTION
	
	This document describes EDIT, a simple, but powerful, screen-oriented
	text editor and word processor for the IBM PC family of computers.  
	
	
	1.1.  Features

	EDIT includes the following major features:
	
	-	A "modeless" editing style, where commands are given via function
		keys, and each command always means the same thing.
		
	-	Support for both insert and overtype (replace) forms of editing.
		
	-	Extensive, easy to use cursor movement commands, including
		movements by character, word, line, sentence, paragraph, screen,
		or movements to arbitary positions in a file.
		
	-	A wide range of single keystroke deletion commands.
		
	-	A set of simple commands for working with blocks of text,
		allowing block deletions, block insertions, moving blocks, and
		saving or retrieving blocks from files.
		
	-	Easy-to-use search and replace commands, including the ability to
		view and optionally replace each instance of a specified string.
		
	-	A wide range of file access commands.
		
	-	The ability to set a variety of text formatting parameters,
		including tabs, margins, page size, headers, footers, page
		numbering, spacing, and right justification.
		
	-	Control over the color of the text display and prompt areas.
		
	-	The ability to save and retrieve the values of settings affecting
		text formatting, printing, and editing.
		
	-	The ability set up a default configuration file, or to specify an
		arbitrary configuration file when EDIT is started.
		
	-	A method for associating settings for margins, page length, tabs,
		and such, with a particular file or group of files.
		
	-	On-screen text formatting, including right-justification of a
		single line, centering, creating bold or underlined text, and
		automatic paragraph reformatting.
		
	-	Optional right-justification of printed text.
		
	-	The ability to print either to a file, or directly to a printer.

	-	The ability to execute any DOS command directly, without leaving
		EDIT (only supported on DOS versions 2.0 and later).

	-	An easy method for defining a macro, a "programmed" sequence of
		commands.
		
		
	1.2.  Execution Environment
		
	The following environment is required to run EDIT:
				
		System:	IBM-PC compatible system.  The XT, At, and
			COMPAQ are all okay.  The PCjr works with
			some restrictions, due to its different
			keyboard.
								
		Monitor:	80 column graphics or monochrome monitor.
								
		Memory:	At least 64K bytes.  96K is prefered.  EDIT
			will use up to 128K if available.
								
		Operating System:	DOS.  1.0, 1.1, 2.0, 2.1, and 3.0 all work.

		Printer:	IBM matrix printer or compatible (any printer
			that supports the ASCII printable characters
			plus CR, LF, and FF).
								

	1.3  Installation
		
	The EDIT distribution diskette contains the following files:
		
		EDIT.EXE  (the EDIT program itself)
		EDIT.HLP  (the text used by EDIT's Help command)
		
	To install EDIT, the user should copy both of these files onto the
	diskette or hard disk that will be used as the default drive when
	EDIT is executed.  Generally, the current "default drive" is
	indicated by the DOS prompt.  If the DOS prompt is
		
		A>
		
	then the current default drive is drive A.
		
	To install EDIT on a computer with two diskette drives, the user
	would place a DOS diskette in drive A, place the EDIT diskette in
	drive B, and type the following command:
		
		copy b:edit.* a:
		
	After copying these two files onto the diskette in drive A, that
	diskette contains everything neccessary to run EDIT.  The new EDIT
	diskette should be used to run EDIT.  The original EDIT diskette
	should be kept in a safe place in case the new EDIT diskette is
	ruined.  
		
	To run edit, the user should assure that an EDIT diskette is in the
	current default drive, and then type
		
		edit filename
		
	where "filename" is the name of the file to create or edit.  Section
	2.2 describes how to run EDIT in greater detail.
		
	The procedure to install EDIT on a hard disk is very similar.  The
	user should copy both files from the EDIT distribution diskette onto
	the hard disk.  They should be copied into the directory that will be
	used as the default directory when EDIT is executed.
		
		
	For instructions on how to create a DOS diskette, and a more complete
	explanation of the "default drive" and "default directory", the user
	should consult the DOS section of the Guide To Operations manual, or
	the Disk Operating System User's Guide.
