Instead of preface.
So, the new operating system. The first question that
usually asked in this regard:
"It's that another IS-DOS?" No
we reply, in a good way
the word is while keeping
due to the fact that if the transition of all
sinkleristov under the IS-DOS is more than doubtful for various
reasons (non-standard format, 48 K nucleus, etc), then
transition of all users under the "PINK FLOYD" more than real.
In principle, the issue of transition from OS
TR-DOS (which the OS and call
complex) has long been important. But the choice of another
system for all a simple question. First
- Who said that this system
for all everyone will enjoy?
And secondly, and what are these
possibility gives another OS to
they exceeded the two main habit and ease? Actually
this issue was already before the
users of IBM PC, they have
also had a problem with the search
worthy of replacing the most stupid, but
most familiar MS-DOS under which besides written lots of
programs (on a qualitative assessment which, however, we are
not talking We will not make because such amizhnika compare
AMIGaDos and TR-DOS). Partial solution
the problem was WINDOWS, similar solution for the ZX
may become "PINK FLOYD" (PF).
Indeed, GUI interface for

where it is caused by a blunt architecture and ZX SPECTRUM
where out of 99 program has a point and the exit

something with which we deal today, and what common
efforts we now have the opportunity to avoid. The computer on

The concept of running "Pink Floyd".
(Included in the system)
Domain OS - is a multi-tasking
operating system with graphical interface standard SAA /
CUA, as well as full support
file systems MS-DOS FAT and
TR-DOS.
Goal of creating a system.
Originally conceived as a
environment for developing computer games (strategy /
adventyury). The main task was to complete
removing the application programmer from the 'iron'. Programmer
must concentrate fully
algorithms on the game rather than engage in plotting the
distribution of memory, looking for a place for the second
break, think about ports, etc. etc. Such issues are relevant to
the creators action games. This is how the disk subsystem
(DSS), the system organization of residents and set
graphic procedures. However,
later wanted more. In
house began to appear about laptop
"Windows 3. 1", "Mac Guide ', and
and then "Windows 95". For Speccy
getting hurt: the PC can
but not on the Spectrum? And through
for some time appeared Application Program Interface via
which was implemented cooperative multitasking. There was an
ideology of object-oriented programming, and from graphic
procedures increased library of graphic objects
(OGL). As a result, there was a complete operating system, with
technologies that were not previously implemented on the
processor Z80.
And finally, formulate goals:
1 User convenience
2 Facilities programmer
3 Transferring advanced technologies
at Spectrum
Multitasking in the Domain OS.
As I've said it a cooperative. This means that while a
computer can be downloaded and run several programs, but these
programs are presented some conditions, full implementation of
which guarantees bezkonfliktnoe coexistence in a single memory
on one screen and one
interrupt handler, a few programs. This is not MagOS, which by
definition can not to guarantee stability.
At the present time, almost every
application contains
a bunch of different components:
character display driver, window system, Filer, mouse driver,
etc. And all this developer spends time and effort. If listen
to the markets of some programmers, we often heard General
Discussion is about the above mentioned components, and not
about the meaning of the program. In the PC world has long been
understood that the important thing to do, and windows are good
at "Winds" or not - Microsoft's problem.
Multitasking can not
burdening the application with numerous features that are not
directly related to the primary goal. I wanted to print text
with text editor - the application sends a message to the
application "Printer" "printer" and print out and wanted to get
a copy catalog disk on paper -
now the "Filer" sends a message "Printer". Thus
Each application is engaged in his own, and only their
business, and the video allows the free exchange of information
between applications. Speaking of the filers. As you may have
noticed, when trying to download a file, you must manually
enter the file name is pathetic. The thing suschestvueschem in
the server drag '& drop. Conceived this way: the user opens the
application "Filer"; finds the file, she clicks
it, instead of the arrow cursor changes to an icon of the file;
The user then switches to the application in which
he needs to download the file, and finally presses the middle
mouse button (Enter). After that boot gone. Many words, but in
reality it is a few mouse movements. Object
Class DLGF, which is responsible
for typing the file name is already working with the drag '&
drop, but the application itself "Filer" esche did not finish,
so when the object called, he can not find the clip
container with the name of the file, and it
have to take the line keyboard input.
Disk subsystem
(Disk Sub System).
At the beginning of the OS domain has been focused only on
the FAT. But the endless conversion with TR-DOS on MS-DOS
tired. I entered the transparent support TR-DOS. That is the
user or programmer any application can not see raznitsitsu
between discs of different formats.
All information about the files transmitted in the format of
MS-DOS.
Programming.
Interaction between application and OS
differs radically from the traditional model: "cool loop,
calling the operating system, come out of the cycle when
something - something will happen. In PF system itself is
"spinning cycle, polling the peripheral devices, and for
example, if pressed, cause the active application, as
their routine. Such an organization is quite possible, since
before 90% of computer time is spent
waiting for user actions. In most cases the reaction of the
applications spend far less time. Thus, the system can be, even
between keystrokes, to spend
bars on their needs. "The main
motto is "programming by PF:
"We quickly made a deal and RET".
The system offers a revolutionary
programming technology the user interface. You only need to
declare an object (display nA display his image and tell the
system that coordinates the data is such - that object), and
you can forget about it. When a user tries to
something to do with the object
System will notify the application. A number of different
communications interfaces can organize any imaginable
complexity in a very short time. I guarantee
that all possible API Windows,
easily implemented in the PF. All that
I wrote the above really
True, but when the number of
display object passes
for the third dozen, there are
problems associated with an accumulation of codes whose
understanding extremely difficult. Therefore,
there was an ideology of object -
oriented programming. It postulates not only
purely formal rules of the program structure and design
(Something similar to the Hungarian
Agreement on the Sea), but also gives
real opportunity to simplify
interface design. Another detail: it is very easy to modify the
code.
This little piece of information
obsolete, but give it without
changes.
Plans for the future.
At this time, three are working
team the following areas:
A graphical editor like
"PaintBrush"
2 text editor

The system has already appeared in Saint-Petersburg. and
distributed through a network of shops firms 'LOGROS Software'
and 'WELCOME Corp.', It is also possible
spread zaimutsya 'SSL
STUDIO 'and' STUDIO X-TRADE '.
Distributed to date version - 2.1. On the way
version 2.3 which will look as it should have been
look at the outset. Press releases are changing frequently and
the differences between them are not purely cosmetic. Members
licensed versions get more from us than bought a pirated
version because getting new releases - free and you spend a
time in licensed, will be constantly
have a new release. Version number
will be constantly changing only at the global innovations.
