       Refinement of GLOBAL COMMANDER.

   First of all I want to ask for forgiveness
from the authors of this knowledge, which I greatly respect,
        changed commander. They created a
        gorgeous commander with a crazy woman
        copy speed and many
        other bells and whistles that stand out
        those who expect it from other similar
        programs. In particular, they apply
        or just an ideal procedure
auto-detection of the presence of a disk in the drive,
comparable only to BEST VIEW. In general,
GLOBAL COMMANDER 1.31i works like a clock!
And I would never, ever climb inside
this program, if not for one “but”...
   It's very bad on the screen of my "Shilalisa"

definitely, because it is printed with attributes

   And such things, by the way, are very spoiled

there are, of course, their merits, but also not
there are also prosperity, and considerable ones (on Scorpio-

presence of the disk in a three-inch drive).
   And so I decided to fix this matter. I have
nya Scorpio with a professional ROM, so it was easier.
Without going into details, for those who have

memory cards in which data on
The print attributes in the windows are as follows:
   #70FD - frame attributes;
   #70FE - in the proprietary version it is there
#45 (blue on black with bright #01) is
attributes of the top right window;
   #70FF - there is #02 (red on black-
bright #01) are the attributes of the second
windows above;
   #7100 - there #43  (blue on black
bright #01) - third window from the top;
   #710B - stands #27 (white on green with
normal brightness) are the attributes of the
lower window, which is displayed when requesting
sakh "delete file?" etc.
   Try going to the shadow market and changing
these values.  The commander interface is possible

   Well, that’s all good, but it’s not

these values! And if there is no shadow worker, then

This data is in the program itself! How is this done?
bark? And this is what I want to tell you...
   Take a blank disc and burn it there
GLOBAL COMMANDER 1.31i. Rename it to
"boot" (this will make it more convenient to work with it
further, less unnecessary movements). Te-
go ahead and run it. GLOBAL will load and you
with its help you cut the file "boot" (class
Vish "U") into two parts with the same name:
"boot.B". The second resulting file is re-
change using the same GC in "boot.C".
 We have two files with a length of 1
sector and into 55 sectors. BASIC part -
this is a bootloader, we are not interested in it, but
the second file, code, is
half-packed code block, and
half - unpacked overlays. Us
You just need the packaged half. Upa-
it was forged using codepackerHRUST
1.0, is loaded into memory from address 42278,a
is unpacked to address 24192 and occupies
after that the volume 9330bytes.
   In any assembler, type the program:

 ORG 24950  ;Here we will place it.
 LD HL, 45000  ;Here there will be a file that
  ;you need to unpack it.
 LD DE, 25000  ;This is the address where we will
  ;unpack.
 JP 23296  ;There will be
  ;unpacker.

   Reassemble it and the resulting code
write the next block of length 9  to your
disk under the name, for example, "depack.C".
Find in your collection HRUST 1.0,
download it and burn the depacker to disk with
name "DEHRUST.C" and address 23296.
 Type the program in BASIC:

 10 CLEAR 24949: RANDOMIZE USR 15619:REM
:LOAD "depack" CODE
 20 RANDOMIZE USR 15619: REM: LOAD
"DEHRUST" CODE
 30 RANDOMIZE USR 15619: REM: LOAD
"boot" CODE 45000
 40 RANDOMIZE USR 24950
 50 RANDOMIZE USR 15619: REM: SAVE
"prog" CODE 25000.9330

   Run this program (if anyone does not
knows how, I remind you: press the "R" key,
then ENTER;-) ). After completing it you
you will have an unpacked code block with
addresses 25000 length 9330 byte, which
the child is recorded on a floppy disk under the name "prog".
It is in this form that it is in the program.

   ...(After writing this article,
BEST VIEW 2.9 appeared for me - amazing
useful and necessary program!Thanks Ivan
Roshchina for the priceless gift! With her help
you can write the unpacked file to disk
without all the above-described frills, simple
by pressing two keys - "SS + ENTER". Not
Just remember, before this operation,
move the cursor to the packed file ;-) ...
   The time has come to make your changes.
Download CONVER COMMANDER version 4.50 and
above. Login to disk doctor, then not-
directly to the file "prog". Why is it named
but this commander? Yes he has the best
disk doctor of all commanders, and,
the main thing is that there is a function of finding the sequence
of the codes on the floppy disk.
   Click "EXTEND MODE", it will ask for
mandu. Press "F" (FIND) and enter after-
the activity you need to find. She

 #45 #02 #43 #45 #01

   In my version I made the upper right
your window with the attribute #44, i.e. green by
black bright #01, second window from the top with
attribute #42 (red on black bright
#01), and the service window attribute from the request -
mi for copying, etc. - #42 (for 9 bytes
beyond the last corrected digit).
   After making these changes, record the track
or just exit the doctor and the program
it will ask whether to record the changes. From-
answer in the affirmative, and on the floppy disk you will
You will have exactly what you need!
   Now download again HRUST 1.0 and from
using it, pack the file "prog" WITHOUT DE-
PACKER. The name doesn't matter, well, for example,
"pack".
 Move the BASIC file "boot" to the end
disk. Let me remind you that its length is 1 sector.
Type the program in BASIC:

 10 CLEAR 24999 : RANDOMIZE USR 15619 :
REM : LOAD "boot" CODE 25000
 20 RANDOMIZE USR 15619 : REM : LOAD
"prog" CODE25000
 30 RANDOMIZE USR 15619 : REM : SAVE
"GLOBAL" CODE 25000, 14080

   As you understand, we simply recorded the changes
the removed part to its original place.
   After running this program we have
we got two files one after another - "bo-
ot.B"  and "GLOBAL.C". The first one is 1 second long -
torus, second - 55 sectors. Try it for-
run the file "boot"  and you will be convinced that
the commander is already working with the ones you need
attributes.
   The last operation is gluing two
these files to get the original look.
In the same commander, mark the two above-
mined file and press "Z". Now
all work is completed! Agree that those
it's much more pleasant with this commander

   And the last thing I wanted to tell you.
This will be interesting for Scorpio owners
with professional ROM.
   It is common knowledge that you can directly from
shadow monitor write or download
any code block from memory without damage
for its contents. Now I'm not with you
I agree! While digging inGLOBAL COM-
