1. INTRODUCTION


EEDraw is a simple parametric drawing program, specifically designed for EE
(Electrical Engineering) type of drawing. The program fully allows new parametric
types, through library mechanisms, and in fact all the EE types are defined this way.
This library mechanism is extremely useful in defining new types and can be used for
other applications other than EE.

The following graphic devices are supported for display: Hercules, CGA, ATT, EGA,
VGA and SVGA (through user provided BGI driver). The following printing devices are
supported (via the printing drivers): EPSON compatible printers (8 pins), PostScript
printers.

Usage: EEDraw [-z] *[FileName[.EED]]

Options: [-z] Print version number and usage.

Quick start:
The program comes with quite common setup. If you have a mouse and a
VGA/EGA/Hercules/CGA then you can simply start eedraw. Typing 'eedraw
82720-1.eed 82720-2.eed' will restart eedraw and prompt you for two windows for the
above two files. Click on left button (return on keyboard) to pick window corners.
Click on right button (space bar on keyboard) if you want to default size (maximum
size). Alt-Q, by default, will take you out.

From version 2.4 onwards a layer structure has been implemented, this will enable the
user to display only the information on the screen they want, also in adding new
layers of there own further detail and notes can be added to a drawing. Hard copy of
drawings show only the layers that were turned on when the drawing was last saved,
all other information is hidden from the printed output.



2. INSTALLATION

 For correct execution of the main program (EEDraw), the following files must exist
in one of the path directories:

     1. EEDraw.exe
     2. EEDraw.cfg
     3. EEDraw.bnd
     4. EEDraw.hlp
     5. *.lib

For correct execution of the printer drivers (EED-PS, EED-Epsn), the following files
must exists in one of the path directories (see also Appendix B):

     1. EED-PS.exe                  1. EED-Epsn.exe
     2. EED-PS.cfg                  2. EED-Epsn.cfg
     3. *.lib                       3. *.lib

The library files (*.lib) are the same for the printer drivers and eedraw itself and
should exist probably only once. See SETUP below shows how to change the setup of
this programs. The default values should be enough to start and learn this program.

3. SETUP


EEDraw set up is done through two files: EEDraw.cfg and EEDraw.bnd.

EEDraw.cfg


This files contain global parameters that should be selected and set only once, in final
installation stage. Empty lines or anything after a semicolon (';') is ignored. This file
is read once when eedraw is being started. Parameters that can be set are:

1. AutoPan -        Boolean flag. If TRUE, any operation involves in the drawing
                    space (such as move, copy or draw) will auto-pan if cursor
                    exists screen.  If FALSE, Panning option must be used
                    manually to perform this operation.  This Boolean flag can be
                    set from the Status main menu.
       For example:
       AutoPan TRUE
2. WindowName -        Boolean flag. If TRUE each EEDraw data file name is printed
                       in the head of the window. If FALSE no name is printed and
                       this makes some  more space for the drawing itself.  This
                       Boolean flag can be set from the Window main menu.
       For example:
       WindowName TRUE
3. ATKeyboard -        Boolean flag. If TRUE, it is assumed AT style keyboard bios
                       calls (also known as Enhanced keyboard - if you have F11/F12
                       on your  keyboard, good chance you can set this to TRUE).
                       This will enable using  more complex scan codes, not
                       supported by regular keyboard (such as  F11/F12). Note
                       however it may HANG your system if it is not so.
      For example:
      ATKeyboard FALSE
4. MouseSensitivity -  Integer flag. Default is set to 10 which is a good  start. Making
                       this number bigger makes the mouse less sensitive.
      For example
      MouseSensitivity 10
5. HVLines -           Boolean flag. If TRUE, lines are coerced to be vertical or
                       horizontal only. This Boolean flag can be set from the Status
                       main menu.
      For example
      HVLines TRUE
6. SnapDistance -      Integer value. Sets the distance in drawing space of   points
                       to be snapped. You probably do not want to change this,
                       especially not in  the middle of a drawing. This Integer value
                       can be set from Status main  menu.
      For example:
      SnapDistance 16
7. Allow256Colors -    Boolean flag. 256 colours BGI drivers will have a richer  set of
                       colours. If FALSE such a driver will be forced to use only 16
                       colours  effectively having same colours are EGA or VGA
                       default colours   (EGAVGA.BGI).
      For example:
      Allow256Colors FALSE
8. AllowAsyncEvents -  Boolean flag. The user interface supports async event
                       handling. This means that one can pop up something while
                       something else  is being popped up already for example. This
                       has the advantage of the  ability to arbitrary "jump" between
                       commands. However this may be VERY  confusing as well.
                       Leave it FALSE at least at the beginning!
      For example:
      AllowAsyncEvents FALSE

9. SaveBackMethod -    Integer. Underlaying windows are being saved for short  life
                       time pop up items such as queries. This integer selects where
                       to  save this data.
      Options are:
      1 - Conventional memory.     This obviously reduces the amount of memory  for
                                   the EE drawings themselves.
      2 - Expanded memory.
      3 - XMS Extended memory      (currently not supported).
      4 - Disk file.               For reasonable response this better be a ram disk.
                                   See also SaveBackPath below.  The device, this
                                   data is saved into, should be able to hold ~100k
                                   for  16 colours BGI drivers and twice that for 256
                                   colours BGI drivers.
      For example:
      SaveBackMethod 1
10. SaveBa
