E-mail - On the prospects of SPECCY: IS-DOS.

   For several years, does not end the debate about the 
prospects further development SPECTRUM'a

Very diverse and often
opposing points of view on
this score and viewers express
our magazine. Published
letter is devoted to relatively
the new operating system, developed by "ISKRA-SOFT".
Many of you directly or indirectly
already familiar with the IS-DOS.
It has its pluses and its
cons. Nevertheless, version 5.0,
in which there is unlimited
formatter (recall that in previous versions it was a counter 
that allows you to make only 8 copies), suggests that the 
period of seclusion was over, and IS-DOS is becoming more

wide recognition and distribution. Therefore, the editorial 
hopes that the letter published below Volosyuk Ivan cause your 
interest and will be the topic for further discussion. 

   So, word to the reader:

   In Kaliningrad on the IS-DOS
few know, but sorry. This
operating system deserves
In order to have it in their own
home. It is known in St. Petersburg and Moscow. It is time to 
Kaliningrad to meet her ... 

    I learned about the operating
system IS-DOS in November
year. Without hesitation, I bought
system floppy disk version of the IS-DOS
3.0, expecting that this is another
Shell TR-DOS'a, and at the root
mistaken.

    Booting, I noted that
The screen is very similar
IBM'ovsky Norton Commander (in
Later, I realized that
IS-DOS shell more flexible
Norton'a). In the upper part
I noticed a list of panels
subdirectories, revealing one of the
them, I noticed inside
HELP subdirectory and realized that
directories in the IS-DOS, not only
present, but may be
nested, as in a normal
catalog system.

    In addition to the subdirectory I noticed
multiple files. I was drawn
See other directories
I have found no less
number of files, and
subdirectories HELP saw
help-files with detailed
descriptions of the files that are executed
type. com. bat. Arisen because of
such a large number of files thought
their inferior
functionality was
refuted by a simple running
some of them. Not
fit in the head, as all
it fits on one
floppy disk!

    A few words about the system:

    IS-DOS is completely different
disk system as compared to
TR-DOS. She has a completely different
structure of the disk
space, another structure
directory, which in addition to
Standard length information
(Which IS-DOS takes 3
bytes), number of initial block
included file attributes, date
last modification, as well as
more stand-byte
and the size of the directory used for a single file, even
over the same area in
IBM'ovskom MS-DOS'e.

    In addition to the IS-DOS'e
entirely different physical
format disk, floppy DS / DD 80
tracks IS-DOS format on
3200 blocks (ie, 800k), then
While the TR-DOS format
On the same disc at 2560 block
(640k), ie 1.25 times
less.

    IS-DOS can work with
segmented files, then
have to separate them when writing to
part. This eliminates
from the team move in TR-DOS'e
(Because of which sometimes occur
various bad things, up to
damage files for errors in the
directory), as well as
segmented nature of the
file based work
IS-DOS Text
editor.

    IS-DOS supports up to six
disk drives, one of the
which may be virtual
disk (it can be created if
you have more than 48k
RAM). For this
target IS-DOS has a large
number of drivers, especially in
recent versions).

    If yours is one drive-no
trouble. IS-DOS can simulate
it work with two or more
drives. For this
enough in the program
blk_tune.com set mask = 0 and
Directory SHELL enter the command
wait / a / b, if the names
used devices: a: and b:.

    Normal screen mode
text (which does not interfere in the
IS-DOS to display the picture:
program exescr.com) 42h24
character, although there
the possibility of switching to
64h24 in the editor (edit.com) and
Text viewer (tv.com),
but to access it to load
Driver ty64.typ, if it is not in
memory after boot.

    By the way say in IS-DOS'e
used a complete analog
alternative encoding GOST
for IBM (ie unwanted tokens
BASIC discarded, and their
place is occupied by graphics and
Russian encoding). In my opinion this
best Russification
Spectum'a.

    For lovers of BASIC in
IS-DOS provides a driver
allows you to get BASIC, in
which added some
function IS-DOS to work with
disc.

    In IS-DOS'e have the means to
keyboard settings on your
taste. You can choose
keyboard drivers on the
several parameters:

  -With an audio signal or not,

  -With the keyboard under IBM'ovskuyu,

  Is one of three types of
Russian keyboard layout on the
keyboard.

    A IS-DOS text
editor, in my opinion, the most powerful
of all the editors
Spectrum, with the most perfect
administration. "

    We note that the views of readers
edition is fully shared.
Indeed, the very powerful
editor. Let's open a little secret: all the text materials for
our magazine is processed
in this editor. But let us continue:
"It allows you to perform many
functions of word processing: from
operations with blocks and macros, calculator,
format to support
several edited files.
The most difficult is the procedure
formatting. It can be
select the appropriate left and
right borders, the regime
automatic alignment,
ignoring or obrabatyvaniya
paragraphs.

    Immediately available funds
Printer-ready text
files in any of several
dozens of types of printers

folder DRIVERS.

    Recently released on
IS-DOS graphic
editor, in which management
more simplified than
with the famous Art Studio. By
he can simultaneously
edit up to three screens.
Descriptions of all the features of this
programs are included in its
help-file in a subdirectory HELP.
However, for operation
graphic editor
desirable to have a virtual
disk, but can be quite
done without it. "

    We consider it our duty to bring
to the attention of readers, that
results of our work with this
editor can say that
editor is a very
mediocre. He was very far
not only to IBM-ovsky "COREL
DRAW ", but also to the 128-th version of" ART
STUDIO ", which we continue to
prefer. Although the Who
knows - maybe next
version of "PICASSO" eclipse all existing image editors? Well, 
we'll just happy.


   "There was among software
