        FIX FAST FORMAT'a.


   I have appeared not so long program that seems interesting 
(sent by reputable ZePagan). Why appear? Yes, because on my 
Scorpio she did not go :-( Wrong poll mouse,

so I have it loaded and "hanging"
not responding to the keyboard. And judging by the
I've seen on the screen, the program with an intriguing name 
FAST FORMAT, developed Vladimiron Cheprasova from 
Dnepropetrovsk, lets you format a floppy disk in System TR-DOS, 
and in the IS-DOS, and MS-DOS (360, 720 and 800 kB), and even 
in the CP-M! 

   It's a shame I was ... Well, I do not have this
"Devaysa, and perhaps never will be,
what am I, and not a man, or what? " (Incidentally,
a similar situation I had with ZXWINDOWS 1.4 ...)

   And I decided to try it to spice up ...
This is what I want to dedicate his note.

   So, using the shadow of his monitor, "Scorpio", I found that 
the mouse can turn off very simply. She queried command CALL # 
9BE5, but is this team at # 9C61. Worth we score zero, these 
three bytes and you're done! The mouse is disabled and you can 
use the keyboard to select options and run! But there is one 
"but" ... It's the most simple thing to do, and after such

blatant interference hardly can tell you
thanks to some Spektrumist which
you give modifed so
program if it has a mouse ...

   Further developed, so civilized! :-)
You just need to insert a space
program a small protsedurku that
detects the presence of "little mouse" correctly and
if one is discovered it when the program starts, it will not do 
anything, and simply pass control to the main program. If such 
devaysa this procedure does not detect, it will score a zero 
most CALL # 9BE5 and the program will work correctly now only 
the keyboard. 

   Now, specific recommendations for those who
faced the same desperate situation,
as I do (and why else would I host a foreign program?).

   With GLOBAL Commander 1.31i or
another way to cut the file FASTFORM
two - the length of 1 and 27 sectors. First -
a BASIC-loader, and the second - it's packed with the program 
HRUST 1.0 code block. Unpack it can be elementarily simple way 
through the magnificent (I can not hide his admiration for this 
program!) BEST VIEW 2.9. Once the file is written to your 
working floppy disk doctor tweak the starting address of this 
code block to # 8000 (32768), and along with the correct 
extension "B" to "C".


   Procedure that correctly identifies
the presence of a mouse, I found in the annex of the newspaper
ZX-Pilot # 36.

   In any assembler files of type:

; Kempston Mouse Interface


        ORG 46355

        HALT

        LD BC, 65503

        IN H, (C)

        LD B, 251

        IN L, (C)

        DEC B

        IN A, (C)

        CP L

        JP NZ, 32768; mouse is!

        CP H

        JP NZ, 32768; mouse is!

        XOR A; Mice do not!

        LD (# 9C61), A

        LD (# 9C62), A

        LD (# 9C63), A

        JP 32768


   Otassembliruyte its object code, write to the disk under the 
name "mouse". Length This procedure will be 34 bytes.


   Now write it down right behind the unpacked Fast Format'om a 
simple program to BASIC'e: 


   10 CLEAR 30000: RANDOMIZE USR 15619: REM:
LOAD "UNPACK" CODE 32768,13587

   20 RANDOMIZE USR 15619: REM: LOAD "mouse"
CODE 46355,34

   30 RANDOMIZE USR 15619: REM: SAVE "NEWFF"
CODE 32768,13621


   The time has come again to pack already changed our code 
block. To do this, download HRUST 1.3, select the cursor that 
Repack the file and it by setting the following Parameters:



   Address Unit - CAT

   Length - CAT


   Decompressor - 32000

   Where raspachit - 32768

   Interrupts - EI

   Auto - 46,355

   Stack - OFF

   DePacker - ON


   The last thing you should do - this is again
"Glue" the first file with the length of a sector and
had only just packed our file length
27 sectors. This can be done by the same GC
1.31i or REAL COMMANDER-ohm or more chemnibud that you like 
best :-) 

   That's it! Now the absence of a mouse does not spoil your 
existence :-) 

   A few words in conclusion about this program. Great prog, 
speed formatting - incredible (faster than me did not come 
across the formatter). What's interesting, I tried to format in 
IS-DOSe - the process was excellent, and the drive is formatted 
to It was already established device

3200 sectors with the name of the disk - ISDOS! Checking doctor 
showed that the formatting was great! (True, spavedlivosti 
sake, I note that in the IS-DOS 1999 , the disk is formatted 
program FAST FORMAT, not defined as IS-DOS '

ovsky when trying to open it :-( In MSDOS'e and CP-M did not 
format because not than check :-( A TR-DOS format

significantly better in quality than, for example, the 
formatter REAL Commander (tested to "zapilennyh" diskettes). In 
general, the program is worthwhile! Try it and see for 
yourself!
