The following information has been extracted from DVED602's internal
reference manual.  I have taken the liberty to do this so that this file
can be made available on BBS systems, for inspection before down-loading
the whole .COM file.  I personally have been using Dr. Dewar's editors for
close to ten years.  I find them to be easy to use, have the right choice
of options, and ARE VERY FAST.    It is my opinion that this one beats all
those other micro and mainframe editors--hands down!  And the best part
for you is that this particular one also happens to be FREE!

This works on the IBM PC and XT, and most look-a-likes, but gets its
speed by going directly into the memory of the monochrome display, so it
might not work if you have a not-so-a-like.

Down-load the complete editor -- It contains all the details you will need.

INTRODUCTION

DVED version 6.02 is a screen oriented editor for the IBM/PC. It requires 64K
memory using DOS 1.1 or 96K using DOS 2.0, and either the color or monochrome
display card. DVED is a product of Realia Inc., written by Robert B. K. Dewar,
and is copyrighted, 1983. It is distributed at no charge, and you are encouraged
to distribute copies of this program to other PC users. Copies of the program
may not be sold or included as part of the distribution of any other product.
However, IBM PC clubs and similar organizations may distribute copies at a
nominal charge for media and copying costs.

This manual is actually maintained as part of the editor file. Entering the
command DVED (with no parameters) causes entry into the help facility which
displays this manual in an interactive manner. In addition, pressing Ctrl F1
during editing also gives help, although on a 64K machine only limited help is
available during editing.


GENERAL ORGANIZATION

DVED works with an input file and an output file. In the case where only an
input file name is given, a temporary file is used for the output during the
edit and renamed when the edit terminates.

The editing process basically consists of a sequential copy operation. Lines are
read from the input file to the bottom of the screen, and written from the top
of the screen to the output file. The screen acts as a window through which all
the data passes, and where it can be edited as it passes. This editing can
involve either the simple retyping of text on top of the old text, or the use of
a variety of special editing functions.

DVED allows the operator to move backward in the file, through a region already
edited and written to the output file. This is done by reading the lines back
from the output file, and writing them to a work file called the hold file. On
resuming editing in a forward direction, the data which has been saved in the
hold file is read back, possibly reedited, and rewritten to the output file.


DOS LOAD COMMANDS

To use the editor, enter one of the following two commands:

  DVED file
  DVED infile outfile

The first form of the command operates like EDLIN. DVED will create a new file
if none already exists, or edit an existing file, with the original version
being renamed with the extension .BAK. The second form of the command edits an
existing input file, creating a new file with the indicated output file name. In
this case no BAK file is created.

In help mode, press function key for details of use.


USE OF ALT LETTER KEYS

ALT C - Clear tab
ALT L - Set/reset left margin
ALT M - Set/reset mixed case mode
ALT T - Set tab

In help mode, press ALT and letter key for details of use.

COMMAND PROCESSING

Commands are entered by pressing the ESC key. This will blank the message line
at the bottom of the screen for entry of a command. During command entry, the
left and right cursor keys and backspace keys can be used, as well as Ins and
Del in the normal manner. In addition Home resets the cursor to the start of the
line, and Ctrl End (ERASE END LINE) is active. Entry of a command is terminated
by pressing the Enter key. Pressing the ESC key during entry of a command causes
the command to be abandoned. See also description of REPEAT COMMAND (End key)
function. Commands start with a single letter (upper or lower case):

  B - Search backwards to key     N - Search to line number
  D - Delete lines         R - Replace string
  G - Global replace string     S - Search forwards to key
  H - Hex data entry         T - Set tabs
  M - Merge file         W - Set word definition

In HELP mode, press the upper case command letter for a detailed description of
the command.


OPERATION OF DVED WITH A MOUSE

DVED can be operated fully from the keyboard. However, it contains features
which allow the use of the PC-MOUSE supplied by Mouse Systems Corp. In help
mode, press the s key for details on the required setup file.


RECOVERY MODE

When an edit is in progress, DVED records keystrokes in a file d:xxx.JOU where
xxx is the output file name, and d is the current drive. If the edit bombs (disk
full, power failure, reboot etc), then the edit can be replayed from this file
by repeating the edit with the /R switch:

  DVED    infile/R       (see reference)

HANDLING OF TAB CHARACTERS

If DVED encounters tab characters in the input, they are expanded to blanks,
according to the standard IBM/DOS conventions.During the edit operation itself,
the tab key may be used to move the cursor across the screen, just as though the
cursor movement keys had been used. The default tab settings (which may be
changed during the edit) are:

  Extension is .COB    T6,10,14,18,22,44,67
  Extension is .ASM    T11,18;40
  All other files      T9,17,25,33,41,49,57,65,73

For .COB files, mixed case mode is also set as the default (see ALT M key). Note
that the tabs for .COB assume that the first 6 columns are not present during
the edit.

Normally DVED uses tabs in the output file where possible to compress blanks and
reduce the space required for the output file, according to standard DOS
conventions, except that lines containing quote characters are never compressed.
If it is necessary to generate the file without any tab characters at all (using
blanks instead), the /N switch may be specified on the DVED load line:

  DVED file/N     or    DVED ifile ofile/N
