INTRODUCTION ***************************************************

 E4 is a powerful multi-file text editor with outlining,
 macros, SVGA support, and in-editor compilation and
 error tracking.

 E4 isn't a bloated every-feature-under-the-sun product,
 rather it is a small, fast editor that manages to
 provide most of the features most people use.

 E4 is great for people who only want to edit
 AUTOEXEC.BAT and CONFIG.SYS as well as Programmers and
 System/Network Adminstrators.

 E4 is a complete Program Development Environment. You
 can compile from within the editor, a single file or a
 whole project. You can also run your program from within
 the editor, with or without a debugger. E4 can shrink in
 size to only 2K, leaving plenty of memory free for your
 program. The registered version of E4 comes with a
 program to trap error messages from a wide range of
 compilers. You can then step through compilation errors
 one by one, the cursor is taken to the erroneous line
 and the error message is displayed at the bottom of the
 screen. This works across different source files and for
 most languages (mixed languages are supported), even
 some linker errors are tracked to the original source
 file. E4 provides a common development environment,
 which ever language you are using.

 E4 really is better than other editors, because it is
 easy to use and powerful. Yes, you have to take the
 trouble to learn it, but once you have got over the
 short initial learning curve it WILL make you more
 productive. Easy to use doesn't have to mean pull down
 menus and WIMPs. E4 works well with a mouse, but the
 common commands are only a single mnemonic keystroke (E4
 doesn't use the function keys: how can they be easy to
 remember?). It doesn't matter if you have "every
 feature" if they are all equally difficult to use. E4
 makes everyone into an expert: the "Hintline" shows you
 most of the commands or options available, at every
 point in the editor. Full context-sensitive help makes
 E4 easy to learn.

 E4 is available as two versions: E4 and E4-Deluxe. The
 Deluxe version is distributed in an archive file that
 begins E4D. E4-Deluxe includes user-definable pull-down
 menus, and the shareware distribution includes more
 sample files.

 Feature lists are not the whole story: that's why E4 is
 made available on a try-before-you buy basis. Don't just
 reject it because it isn't exactly the same as what
 you're using: try it!

 E4 already has a large user community including
 professional programmers, businesspeople, educators, and
 students. If you've got a suggestion or problem call the
 author (Neil Faulks) on 071 873 2007 ([phone])
 anytime, or mail him on the Internet
 ([e-mail]) or through CompuServe 100417,1251

 I want you to be happy with E4, before and after you buy
 it.

IMPORTANT NOTICE ***********************************************

 This is a Try-before-you-buy Evaluation copy of the E4
 Editor, it is fully functional. You may use E4 freely
 for up to 30 days, but if you want to use it after this
 period you must pay for it. See later in this file.

 Occasionally the editor will ask you to press a key when
 you first run it, this feature is absent from the
 version you will receive upon payment.

 Buying your own copy also brings the benefits of
 comprehensive printed documentation, extra utility
 programs and macros, and special offers on upgrades and
 other products.

 Programmers should note that only the registered version
 supports compiler error message tracking, as it requires
 extra support programs.

PACKING LIST & RELEASE NOTES ***********************************

 This software should be distributed as the single .ZIP
 or .EXE archive. The archive contains the files listed
 below. PLEASE KEEP THE ORIGINAL ARCHIVE FILE TO GIVE TO
 OTHERS.

 Note that if this is the E4-Deluxe distribution more
 files are included than are listed here.

 E4.EXE        The Editor itself (All you really need!)
 E4.HLP        The help file for the editor
 E4KEYS        A sample keyboard mapping file
 E4.DOC        This document, Please read it all
 E4ORDER.TXT    Printable order form and prices
 VENDOR.DOC    Notes for shareware vendors and BBSs.
         Includes feature lists and descriptions
 FILE_ID.DIZ    A BBS description file
 TEMPLATE.C    Sample template file for C programs
 E4OPTS.C    Sample options file for C programs
 COMPILE.EXE    A generic compiler control program
 COMPILE.DOC    Documentation for COMPILE
 COMPILE.CL    Configuration file for COMPILE

 The sample E4KEYS file includes some key definitions of
 use only to programmers, to handle in-editor
 compilation. These are distributed as macros in the
 registered version, but are included here in the keys
 file to save space. The sample definitions allow you to
 compile from within the editor (a single file or a
 complete project), and to execute your program with or
 without a debugger. The registered version provides full
 error tracking, allowing you to step through error
 messages one by one, taking you to the correct file and
 line.

 Programmers should examine the E4KEYS file to learn
 about creating macros to compile and debug programs.

CHANGES ********************************************************

 Only major changes are listed, numerous minor changes
 are made with every release. The registered version has
 more detailed information.

 Version 2.03

  key is pressed or the mouse is moved over it
  (E4D). Setting a default extension now disables
  the "Create Project File" prompt.

 Version 2.02

  E4PATH enhanced so that * (meaning the current
  E4.EXE directory) can appear within a pathname.
  Default E4PATH changed to prefer placing config
  info into a CONFIG directory if one exists.
  Network users can as always have their own local
  config if the HOME environment variable is set.

  Added support in COMPILE.CL (shareware) and
  E4TRAP (registered version) for Procomm ASPECT
  language.

 Version 2.01

  Minor changes to documentation. Inclusion of a
  DESCRIPT.ION file for 4DOS and V1 users. No
  changes to programs, other than date and

  First non-commercial release.

OVERVIEW *******************************************************

 E4 will run on any PC compatible with 128K of RAM, under
 MSDOS 3.0 or above, and any standard display adaptor. A
 hard disk is not required: the minimum installation is
 about 40K (42K for E4-Deluxe).

 SVGA support allows for special text modes such as
 100x40, 100x75 and 132x60, on those cards that offer it,
 up to 255x255.

 Full use is made of enhanced keyboards including F11 &
 F12 and other special key combinations. Full mouse
 support (for a true Microsoft compatible mouse) allows
 on screen selection of text and menu operation. Note
 that mouse support in SVGA screen modes often does not
 work due to mouse driver limitations.

 The editor occupies little disk space making it suitable
 for installation on a RAM Disk, the optional help file
 can be relocated elsewhere; using the E4HELP environment
 variable.

 E4 has a short start up time and loads and saves files
 very quickly.

 Most of the keys on the keyboard may be redefined to
 suit you. Any standard key combination, or pair of keys,
 may be assigned to one or more editor functions, simply
 by editing a text file listing the assignments to be
 made (E4KEYS). A command line switch can be used to
 override customisation so that someone can use the
 editor on another person's machine, for example when
 giving help in a school or college.

 The normal Cut and Paste system, which allows arbitrary
 streams of characters to be moved about the editor, is
 augmented by a simple system for moving and copying
 whole lines, as this is such a common operation.

 A design limitation is that the maximum file size that
 may be edited is 64K, and is one reason the editor is so
 small. This limit is offset somewhat by the ease with
 which multiple files may be edited. In particular you
 are able to perform a truly global search and replace
 operation that affects several files. When programming
 it is not a good idea to construct a program by using
 one monolithic file, better to split it up into several
 modules.

 E4 comes with complete context-sensitive on-line help.
 But you can use page-up and page-down to move through
 the help screens one by one if you want to make sure you
 see them all. Press F1 twice to find out how to use
 help.

INSTALLATION & RUNNING *****************************************

 DOS 3.0 or above is needed to run E4.

 Copy the files listed in the packing list above to a
 directory on your hard disk and put that directory in
 your PATH. For example if you create a directory for the
 editor called C:\E4 then you should add the following
 line to your AUTOEXEC.BAT file (and reboot):

     PATH C:\E4;%PATH%

 If you have CED or ANARKEY or a similar command line
 editor, you can have an alias that expands to the full
 pathname of the editor, instead of adding the editor
 directory to the PATH. E4 does not need to be in the
 path to find its support files or programs.

 Run the editor with the list of filenames you wish to
 edit. Wildcards may be included:

     E4 \AUTOEXEC.BAT \CONFIG.SYS \WINDOWS\*.INI

 NOTE: A few systems may not correctly identify the type
 of keyboard they have: if the editor hangs then reboot,
 and run it again with the /P switch, which forces it to
 use only the standard (PC) keyboard driver, rather than
 the enhanced (AT) driver. Note that the editor has been
 tested and does work correctly on true IBM PCs, IBM
 PC/ATs and IBM PS/2s, as well as many machines from a
 variety of manufacturers including Compaq, Dell, Grid,
 NEC and Tandon.

 The /B command line switch will run the editor in black
 and white. /? will list other switches.

 F1 displays context sensitive help.

 Press ALT-Q to leave the editor.

 You can put standard switch settings into the E4
 environment variable:

     SET E4=/B

 The example above will cause the editor to always run in
 Black and White.

 You can have many options listed in the environment
 variables. For example, if you also want to use CUA mode
 (E4-Deluxe only) you would set the variable like this:

     SET E4=/B /=CUA

 These SET statements are best placed in your
 AUTOEXEC.BAT file.

DEMO ***********************************************************

 For a short demonstration of Resume Mode go to the root
 directory of your boot disk and (assuming E4 is in your
 PATH) type

     E4 /R AUTOEXEC.BAT CONFIG.SYS

 Then press ALT-Q to quit the editor.

 Now whenever you want to edit your configuration simply
 go to the root directory and type

     E4

 The cursor will be where it was and the same files will
 be loaded. Any new files you load will also be available
 to future sessions.

EXAMPLE APPLICATION - BORLAND PARADOX **************************

 If you use Borland's Paradox (3.5 or 4.0) you can
 install E4 as the default editor. Use the following
 command line:

     E4 /XSC * /**

 This sets the default extension for loading and saving
 to .SC (for script). Paradox replaces the * by the
 filename and the ** by a line number within the file (E4
 interprets a number after a slash as a line number to go
 to on start up).

SUPPORT ********************************************************

 Technical support is available directly from the author
 by Post or E-Mail to any of the addresses given at the
 foot of this document. E-mail is preferred.

 Support is available whether or not you are a registered
 user: We want you to be happy with E4 before you buy it.

ORDERING and PAYMENT *******************************************

 This software has been made available so that potential
 users may try it out before committing to buy it. If you
 think that you have already paid for this software then
 you have been mislead by whoever took your money. Many
 organisations charge a copying fee for providing
 evaluation copies of software like this, which is
 legitimate within the limits detailed in the VENDOR.DOC
 file. Others, who may also be charging a higher fee, do
 not make it clear that you are paying them a service
 charge for providing you with an evaluation copy of the
 software.

 You must pay for this software if you continue to use
 it. This is copyrighted commercial software. The term
 "Shareware" is often applied to software marketed in
 this way, but it must not be confused with free software
 such as that in the Public Domain (PD).

 To pay for this software please examine the file
 E4ORDER.TXT, which is a registration and order form. You
 can fill this in before or after printing it out.
 Alternatively any form of order may be used provided
 that all the information requested in the text file is
 provided. Always quote the issue number given on that
 form (the same Issue Number appears in the editor banner
 screen).

 In exchange for payment you will receive a version of
 the software without the registration reminders, and
 which is registered to you personally. The price
 includes both E4 and E4-Deluxe, a comprehensive printed
 manual and extra utility programs and macros.

 Note that this registered version may not be distributed
 in any way and must be treated like any other commercial
 program. Please refer to the licence agreements below.

EXTRAS *********************************************************

 The following extra programs (at least) are shipped with
 the registered version of the editor:

 E4SM    a program to set special text modes on VGA/EGA
     cards. It also analyses your VGA card to find
     out what special text modes are available.

 E4TRAP    a program to trap error output from a range of
     compilers so that E4 can perform error tracking.
     Currently supported compilers include Borland
     C/C++, Turbo Pascal, Turbo Linker, Turbo
     Assembler, Microsoft C, MASM, Fitted Software
     Modula-2, Zortech C/C++ and others. Other
     compilers will be added in the future.

     Many compilers that are not listed will also
     work, if they generate standard error messages.
     Contact us if your compiler is not listed, we
     will add it if necessary.

 E4PRINT    a program to print E4 wordwrap files (and
     ordinary text files) on normal and PostScript
     printers.

 A library of useful programmer's macros is also
 provided.
