    Hello, dear readers.
Today, under the heading "IS-DOS - users", we begin publishing 
the magazine version of the new book, which is currently being 
prepared for release in the company Iskrasoft. We do not know 
what will be This book will come out whether it is in printing 
option, or as a reference system on the disk, or in some other 
way. In the meantime, we offer

the first few chapters of it and hope
they interest you. If you, dear readers, to deem these materials
interesting and worthy of publication,
then in the next issue we will continue our conversation.


    Sincerely, Department of IS-DOS.

   UTILITY OF BASIC KIT IS-DOS.


                INTRODUCTION.


    This guide is based on help-files base kit
IS-DOS, written, mostly, AG
Leontief during the existence of the system from 1992 to 1996 
inclusive. Sources were significantly redesigned specifically 
for this handbook B. A. Eliseev, mainly to make them more 
readable, error correction and interpretation of certain 
fragments of texts, obscure wide mass of users.



    This book does not repeat the well-known edition of the 
Moscow firm "slot", and is rather an alternative

this once "necessary and timely
book, now, unfortunately, hopelessly
obsolete.


    Descriptions of commands and utilities IS-DOS are in the 
book in alphabetical order. Separately considered resident

programs and their com--native counterparts that perform the 
same function, the program will print a text editor, Decoders 
files, device drivers. For each program in the header 
corresponding Article shall specify the date of the last 
edition of the file (at the time of writing) and name of the 
directory in which it resides. 


    Let's start in order:

Block approach is up
--------------------------------------

    The basic program abba.com and its modification acca.com 
and adbc.com designed for rapid duplication of CDs IS-DOS on 
the two drives. They carry out the so-called "scaling in" copy, 
where the output (in which you want to copy) the disc by its 
logical structure is completely identical to the input (from 
which the copy).



    This way of copying is very convenient for novice users, so
how to create a working copy of any IS-DOS disk, not caring
neither its content nor about how to connect
system files, and creating a system
loader.


    Three variants of the program work exactly the same and 
differ only choice of the output drive. Each of the

these programs working with certain
pairs of devices, with output drive is automatically selected, 
depending on the version of the program. 


    Program abba.com copy disk
located in the open on the current panel of the device (on the 
current panel may be open to any directory of the disk)

disk, located in the "next" device, ie, the pairs are formed as 
follows: 


          from A to B, from B to A,

          from C to D, with D on C

               etc.


    Program acca.com copy disk
located in the open in the current of the device to the disk 
being "a one" device, ie, formed pairs are as follows:



          from A to C, from C to A,

          from B to D, from D to B

               etc.


    Adbc.com program differs in
that works with the following pairs of units:


          from A to D, from D to A,

          from B to C, from C to B

               etc.


    All possible combinations are given in
Table. 1

    Thus, to perform the copy you need to open on the current 
panel input device to select and run one of copiers, depending 
on what device you needed to insert into the input device

disc source, and output - pre-formatted program
format.com CD-receiver.


    Starting copiers most convenient
to produce "hot key", previously described in a text file
extkey.txt (how to do this, read the book and VA Eliseev, 
"IS-DOS - The first acquaintance "). Usually the most

often used copier abba.com
attached to the key "w", and more
rare acca.com - to the key "W". You can also run it from a 
command line monitor, such as: 


     Q: UTIL \ abba


    Office of Emergency Programmes
simple - after running on the screen appears the following 
window: 



     Copy all from <N1> to <N2>

     <Y> Or <Enter> to continue

     <N>   To quit


where N1 and N2 - respectively, the symbolic names of input and 
output devices. 


    By following these guidelines you can press Y or ENTER, to 
perform the copy, or press N, SS + A, SPACE, to abandon the up 
and quit. 


    WARNING! Programs are not checked for
    The presence of previously created devices on

    output drive, so if you up for
    We first copy there was a kind of no
    whether the information, all of it will be morning
    Chen.


    The copying process is shown in
bottom of the screen with a running
band. When the program is copied
contents of an entire disk, excluding only
continuous free space
end. The maximum operating time depends on the size of the 
occupied area on the disk and is 2.5 - 3 minutes. Input and

output drives must comply with
each other by the number of sides and tracks.


    Programs chunked up can not only work with drives, but
and any other block devices (eg, disk or electronic
hard drive). It is only necessary to remember
These programs overwrite without modification all of the 
information drive, including the contents of system paths, so

if the output device is different in
number of blocks of input are possible
various uncertainties due to the fact that
size value will be directly rewritten
Disk-source.


    For example:

input device A:

    IS-DOS disk 800K 3200 blocks
output unit C:

    Ramdisk PROFI 3500 blocks

as a result of the program
acca.com size RAM disk will be equal to 3,200 units, which will 
lead to loss of 75 kilobytes of memory. When copying from 
floppy to hard drive results may be even more sad.

Verification of the file structure of the disc
--------------------------------------

    The program is designed to arzt.com
verification and automatic correction of the file structure of 
disk devices. She verifies information about the location of 
files contained in their descriptor (the catalog) and the 
so-called "employment card drive and allows you to diagnose 
errors file allocation, such as: "lost" blocks, crossing

files, etc. Most of the errors, suggesting unique solutions, 
are corrected automatically. 


    Arzt.com program can be very
useful when working with disks, survivors of crashes when the 
records that contain "broken" files, etc. In addition, its 
application is necessary after removing files and directory 
utility remote.com (see) 


    The program can be run either directly (by pressing ENTER 
on behalf of programs), and from the command line

or "hot key". The base kit IS-DOS this program is attached to 
the key "z". 


    After starting the program on the screen
Menu window appears as follows:


               DISKNAME

               Device: N

               Start

               Repeat

               Write BM

               blk: 3,200


where DISKNAME - the name (label) of the current device N - the 
symbolic name of the current device 


    To select a different device, you just place the cursor on 
the line "Device", press ENTER and enter the symbolic name of 
the desired device (the letters A through H). In this case, 
previous line will be printed label disc.



    To get started, you must select the option Start. The 
program starts to scan the file structure disc, showing the top 
of the screen two windows. At the top is displayed the way

to scanned at the time the directory
a slightly lower - the number and name checked at the moment a 
file or directory. 


    If the file structure of the disk in the order, the program 
completes its work, reporting finally in a window on

bottom number of the last occupied block and file name to which 
this block belongs. You can stop the

the program on a particular block,
specifying its number in the menu bar, "blk"; for
This set the cursor on that line,
press ENTER, type the number value
block and press ENTER again.


    If the program detects a discrepancy between the file 
structure of the disk map employment blocks of this device, as 
well same when the block number indicated in the row "blk", the 
program halts with a message in box in the upper right corner 
of the screen. In this window, three rows. Their content 
depends on the situation. The first output name and file type, 
which belongs to found block. If the block is not found

belong to any file name, of course, is not displayed.


    The second line displays a message about the situation. The 
following options: 

LOOKED - found the block belongs to a file whose name is shown 
at the top line of the window.


LOST - "Lost" block, the block
owns a file whose name is shown on the top line, but the map 
units of employment, he is listed as free. 

CROSSING - block belongs to two files
simultaneously. In the derivation of such a message at the top 
of the window shows the name the second of these files. Name of 
first file, you can find out if you run the Start again with 
the line number of the detected block blk. The program stops 
when finding the first mention of this

block and displays the name of the
file.

FOUND - unit does not belong to any
from the files, however, the map of employment
blocks, he is listed as busy.

WRONG NAME - incorrect file name or
directory, this situation arises when there are errors in the 
descriptor file or directory. 


    Simultaneously with the withdrawal of these messages 
displays a window with statistical information about the 
current number of "irregular" units in three main situations - 
Lost, Cross and Found. 


    To keep the program
After the stop, press
any key. In this work program will continue until the next 
stop. If you do not want the program to stop when it detects 
errors in the file structure, and continued collect information 
automatically, you can then stop pressing CS + ENTER.

If you do not want to continue scanning - then SS + A, and you 
will return to main program.



    After scanning, as already
mentioned above, shows the number of the last occupied block 
and file name that owns this block. In addition, the statistics 
window stores information about the total number of errors 
found in each of the three main situations. 


    After the scan is complete you can again see all arisen
error situations with the option
"Repeat". Each press ENTER on this
line is about the next
error. Pressing the CS + ENTER causes rapid "scroll" the 
information without stopping. 


    Errors of the LOST and FOUND can be
corrected program independently.
For this is the option "Write BM". She
A map of disk blocks in employment
According to the information contained in the file descriptor. 
Type errors CROSSING require logical thinking

and can not be corrected automatically. Moreover, the 
correction of such errors - the work is complex and

ungrateful, so in this case
the best solution is to delete both files and
replace them with backup from another disk.


    Arzt.com program stores the data on the last processed
drive up until you leave the
it does not run the "Start" on another device or do not do the 
option "Write BM ". If you need to simply reset this 
information - click on ENTER the top row with the label-name 
the current drive. 


    Option "Repeat" and "Write BM" work only after finding the 
error, if error information is missing - the cursor will just 
"jump" through these lines. 


    To exit the program you can use a standard combination of 
SS + A, to get to the root directory and press SPACE, to reach 
the same directory that was current at the bar at the time of 
starting the program arzt.com.

Check the file structure
and sealing drive
---------------------------------------

    Program arzt +. Com is a modernized version of the program
arzt.com. This version has a new option - SQUEEZE. She fills 
every open space in the middle drive by moving back the 
following files. As a result, all the free space on the disk 
becomes continuous.



    In this regard, several changes
menu:



               DISKNAME

               Device: N

               VERIFY

               Repeat

               Write BM

               SQUEEZE

               blk: 3,200



    Option VERIFY - performs the same operation as the 
arzt.com, namely - check the file structure of the disk. Option 
SQUEEZE - starts packing procedure, the rest of the line 
remained unchanged, with their work you are already familiar to 
description arzt.com. 


    Another small difference: programAL (mp + ma arzt +. Com 
does not show at the end Scan number of the last occupied

block and file name, but instead counts the number of segmented
files on the disk and the total number of segments
in them, bringing this information to the bottom
line of the screen.


    Now consider in more detail
process of sealing drive.


    For a start - a few important comments and useful 
suggestions that are better read before the start of the 
program: 

1. SQUEEZE option works on any block devices IS-DOS, provided 
that do not exceed 1 MB (4096 blocks), so its use on the hard 
drives of more than problematic. 

2. It is important that the disk was not
bad or ill-read sectors, even if they are marked as bad program 
bad.com (see) This is because, that the program can move files

*. Bad in another place, among others, that
can lead to unpredictable consequences, in particular the 
appearance of Crossing'ov and loss of information. If you

not sure 100 percent reliability
Your hard drive is recommended before sealing it with a program 
processing doctor.com (see) in the mode of Restore. 

3. Once again, be warned - do not compact discs containing 
files of type *. bad. This can cause damage to files and 
trudnoustranimye errors. It is better to rewrite Google
