          1. Overview.


 Screen Editor Software Package
designed to create screens to
game programs. The screens are constructed from
individual elements. All the elements are
the same dimensions. Element size
can be from 1 to 6 as the familiarity of
horizontally and vertically.
The maximum screen size - 32 to 24
familiarity, ie, Full screen
Spectrum, minimum - 1 of 1
familiarity. The maximum number of
elements may vary
the size of the latter, but not always more
255.

        4.1. Initialization.


 Submenu 'INITIALIZING' gives
opportunity to:
 - Specify the size of the element of
horizontally and vertically;
 - Specify the size of the screen horizontally
and vertically;
 - To clear all items.
 and installation of new dimensions
elements are automatically
change the screen size (screen size
becomes equal to the size of the element).
Therefore, the installation size should be

always a multiple of the element. When
activation of the item 'CLEANING ELEMENTS'
program will ask for confirmation. In
If the answer is
NeuStar zeros in black and white part and the number # 47
in element attributes. Select 'OK' - output
the main menu.


       4.2. Work with the layout.


 This menu is for
'Pulling out' of elements from
full-screen picture of the layout
(Drawn, for example, ART STUDIO)
 To do this you must first
download the screensaver.
 Submenu has three windows. The biggest
maps of the layout, two smaller ones
show the element under the cursor layout and
current element, respectively;
size of the latter are identical and equal
dimensions shown in the submenu
'INITIALIZING'.
 After selecting 'MODEL' can be
move the cursor around the screen saver. In the left
top right corner indicates the current
cursor position. Output - a key '0 '.
 Item 'THE BANK' makes removal of the

vice versa. Select 'OK' - exit to the main
menu.


 WARNING! If the screen is used
 'Empty' element, then the number should
 be '1 '.
 In order not to inflate the file elements
 Use all numbers without spaces.
 For the convenience of compression screens

      4.5. Working with the drive.


 This submenu contains the following
items: 'Reading Layout' READING
SCREEN ',' read items ',' ENTRY
SCREEN ',' ENTRY ELEMENTS 'and' OK '.
Appointment of all these items, I think
understandably so, but at some points
should stay in more. For all
Readings will be prompted to insert a disc
and press '0 'and then be read
directory. Each of the three readings of 'looking' at
drive only specific file types.
So in reading layout in the list will be
made only code files length 6912
bytes when reading the screen - the type of file
*****. Sc  and reading elements -
Files of type *****. el . In the case of
lack thereof will be issued
appropriate message and the program
return to the main menu. If the file (s)
there is, then any of them can be downloaded
by moving the cursor and pressing '0 '. In
the end of the file list will contain the string
, Calling that can go
the main menu. When recording a program
ask you to enter the name (five characters). If
file with that name already exists, then
there is a possibility perezapistat his or
refuse entry altogether.


WARNING! If you plan to
 compress screens
 using SEComp, the names of
 All files should be:
 **+++. Sc , where ** - any two
 symbol + + + - three digits. Where '**'
 must have all the files the same way!
 '+++' - Further there should be more
 the previous unit, for example, 149
 150, 151. For examples, see paragraph
 'Delivery'.



      4.6. VERSION NUMBER.


 Version number - the next item
Program Screen Editor. As follows from
titles in this section can be found
the version number of the main program package.
At the time of help-file is
DEMO VERSION and V1.0.



       4.7. EXIT.


 When you activate this menu
frame appears to items: 'SOS'vyhod in
Wasicka, 'DOS'vyhod in TR-DOS and run
boot'a, 'NO!' return to the main menu.
It should be noted that when you exit
Program mode (48 or 128) does not
changes.



       4.8. Application.


 The package includes an application consisting
of the five files and displays the file
elements. All this can be posmotret.Dlya
This need to download Screen Editor,
set (item 'INITIALIZING')
size of 2 * 2, the screen size
32 * 18 download (select 'OPERATION
DISK ') file elements, any of the
screens and enter the 'EDITOR SCREEN'.



        5. Scissors.


 The second program of the package
designed to handle file
elements. The fact that the program
Screen Editor always upload files
*****. El of the same size -
14400 bytes (12800 bytes b / w images and
1600 bytes of color information), but not
14,400 bytes are always those used by
100%. Therefore, the program Scissors
reduces the file element to the minimum
sizes.
 Downloading and management does not differ from
previous program. The program only
two items: 'Optimization' and 'Exit'.



       5.1. Optimization.


 After activating this menu item
the program will ask to insert the disk and
press '0 'and then will be displayed
a list of all available files with
extension. el. Refuse to load
You can select a row . When
download is complete the menu appears, in
which must specify the size of the element
type of optimization (1 or 2), number
the last element we use and
click on 'OK'. The next wish
program will be a file name for the shipping
optimized elements. In the case of
Repeat the name issue is solved as in
Screen Editor'e.
 Now about the type of optimization. Type 01: B / W
1, b / w 2 ,..., b / n, tsv1, tsv2 col ,..., n.
Type 02: B / W 1, tsv1, b / 2, tsv2 ,..., b / w
n, col n.



        5.2. Exit.


 See paragraph 4.7.



        6. Screen Editor Compiler.


 The ultimate goal of the work on the screens
is their compilation, which saves
computer memory when using
screens in the game programs. Compiler
creates two files. One contains all the
you mentioned the compressed
screens, and the second offset table
needed to find the right
ekrana.Takzhe as in the previous
program, here are two items: 'KOMPILYaTsIYa'i
'Exit'.



       6.1. Compilation.


 After activating this item
you must enter two names. File name
the first screen and file name of the latter.
The program checks the first two characters names
and checks that the 4, 5 and 6 characters names
were figures. After the successful entry of names
program reads the directory of the drive in
memory, and starts compiling. When
compilation issued the following
Information: Order number, name
kompressiruemogo file, the file length before and
after compression, the compression ratio (in
percent), the length of all
uncompressed and the length of all
compressed screens.
 Abort the compilation, you can click
. If any file is
absent from the disc, then you will receive
Message: 'FILE NOT FOUND *****. sc.
COMPILATION CONTINUE (Y / N)? ". When
receiving a positive response will be
re-read directory of the drive and continue
compilation. This helps in the case
if the files are scattered in different screens
disks.
 After the end of the compilation, enter
name for the shipment.


WARNING! At compile time, not
 controlled by the length of the screen in bytes
 therefore, the length should be the same.
 The amount of memory when compiling the limited
 and therefore need to make sure that the length of
 all the compressed screens do not
 exceed 30K.



     7. Program EXAMPLE .


 An application package including the procedures
written in assembler (TASM format
3.0), which demonstrates
zakompressirovannye earlier screens. For
This requires:
 1. Edit the file dz. El 
program Scissors (the size of the
2 * 2, the type of optimization - 02, last
used by element - 108) and unload
under the name example3 ;
 2. Compiled from five screens
Applications (dz000.el - dz004. el) and
unload named example (in fact
actually written two files example1  and
example2 );
 3. Run TASM 3.0 (or MASM),
download EXAMPLE , otassemblirovat
and <RUN>.
 The text of the procedure, there is little
comments.
 I wanted to write this procedure
as clear and legible,
therefore, its speed leaves much to be
desired.



    8. Any useful information.


 File screen consists of
sequence numbers of elements,
located on the left - to right and top -
down. Thus the length of the screen
bytes is the product of
elements horizontally by the number of
elements of the vertical and is always greater than
zero and less than or equal to 768 bytes.
 File elements, as stated above,
always has a length of 14,400 bytes each
element is filled with information on the left -
right, top - down the line (as
b / w and color components).
 Compression of screens is to replace
repetitive numbers (Є3) on
sequence of the form: 0, which is much
times. All other information
transferred one by one.
 All disk accesses are made through
standard procedures ROM and in the case
any error (DISK ERROR, NO DISK, READ
ONLY, ETC) will not know that.
 The second file is created SECompiler'om
(File offsets) contains
information about the location of all
zakompressirovannyh screens.
Example of use:
 LD A, 2; number needed screen
 LD L, A
 LD H, 0
 ADD HL, HL
 LD DE, # 8000; to 'DE' top of file

                 displacements
 ADD HL, DE
 LD E, (HL)
 INC HL
 LD D, (HL)
 LD HL, # 9000; in 'HL' Home

                 the compressed

                 Screens
 ADD HL, DE; now in the 'HL' address

                 the desired screen


           9. Glitches.


 While in the program package found one
minor bug:
 If the difference between the length of the file before and
after compression is large (more than 600 ¢
B), then it may be incorrectly counted
compression ratio.


WARNING! If you find
 any bugs or want something
 to say or wish the author, write to
 and call.
 Proper versions will not work kryaknuty
 guaranteed.



          10. Version.


 As stated above, there are two versions
Package: Demonstration version V1.0.
V1 .* version will appear in the event of a
any significant changes.
 Perhaps soon a new package
programs (V2. *). It will differ
the possibility of using elements
unfixed size. About
half of the toys using screens made of
elements unfixed size. In
Screen Editor'e V2 .* probably will not be
item editor (and it byloby
similar to ART STUDIO).
