Automobile assembly program
A lot of prejudices and poor decisions in such a seemingly
natural and long mastered the problem of how assembly programs.
By itself, the assembly phase cases not even for every program
(Eg, for such I may say,
software, on what learning to program, and he does not need
one), but the need to release versions of the series, he
becomes one of the questions most
waste of time.
A single assembly is traditionally carried out by
discharging stored after compilation (chunks or sploshnyakom),
and then received blocks packed by hand in arbitrary
compressors, and then sutured to a packed program of any known
BASIC loader. Way so traditional, that appeared relevant
function (unloading blocks and gluing) in the
Many assemblers - the first - and
Commander - for the second. However, even such seemingly,
automation does not prevent time-consuming. In practice
method is comparable with manual discharge STS'om
and manual correction of the same directory in it -
at least, the various programs rarely
want to download.
Detailed explanation (of the traditional
assembly).
Builds the project was originally expected to being in a
form suitable for zapuska.Delaem debug it the following
Added: addresses beginning and the length of the terminal block
assembly directive DISPLAY; if possible, it is best to collect
all the blocks in one block, and the program during startup
should flip their LDIR'om (LDDR'om) on the right places, and
the address is supposed to be running too directive DISPLAY.
That is so that after all the necessary addresses ASSEMBLE
light on the screen, where they can sleep write down on paper.
ASSEMBLE after all these blocks need to save through STS
(click S), or through DOS (SAVE "..." CODE ...,...). Next
computer must be reset to load kompressor.Etim compressor need
to pack blocks (all - with the unpacker, if we are talking
about the traditional way).
It remains to form a BASIC loader,
which has two main options - one-piece and made
pofaylovyy.Pofaylovy entirely in BASIC: CLEAR: LOAD, LOAD, LOAD,
then USR + USR + USR ... here and there, perhaps, OUT
32765 ... Just keep in mind that between
OUT 32765 and relating to this page
LOAD'om (or USR'om) should not attend any other operators - or
128 BASIC can switch the page but the reverse.
Monoblock loader contains only
(Optional) CLEAR, USR, and (again optionally) REM, with plenty
of gaps. In these gaps STS'om fits loader code type LD DE,
(23796) ... CALL # 3D13. Recruit a boot rather tedious.
Unpleasant as the fact that after keeping the boot disk must
copy after all the related it zipped files. Then the program
Global Commander (or any other
in which you may have to copy them)
files are glued to the candy bar. To a large
failure, Perfect Commander 1.52 from the
Gluk Reset Service v5.4R glues files
wrong. In Gluk v5.5RR it fixed.
The positive side of monoblock loader and that he is shorter.
And restrictions on the inclusion of pages already
No, especially if the reinsured team LD (IY +1), # CC (in any
case, it is established that this team does not give IM 1 port
# 5bxx). Incidentally, it was in it, so the loader can provide
a general unpacking of all code blocks. Convenient, for
example, the classic DEHRUST for Hrust 1.3 - This depaker
weighs exactly one sector.
Monoblock program with a total depakerom
You can reduce and even stronger if all
compressed blocks glued byte to byte. This de barks already in
assembly language:
LD HL, pack1
LD DE, depackto1
CALL DEHR
LD HL, pack2
LD DE, depackto2
...
DEHR INCBIN "DEHRUST
pack1 INCBIN ...
pack2 INCBIN ...
...
Do not forget! Memory at startup is not necessarily clean,
not included necessarily page # 10, and more!
End of explanation.
What is this said assembly STS'om?
Originally it was unloading code blocks without packaging (with
the address to peek into assembly label) after the first copy
BASIC-unit - for example, over the old building of the same
programmy.Beysik block would have to download as a sector
change in it that has changed (such as your start-up program)
and keep on top again, as a sector. This Release inconvenient
for distribution, but is going very quickly - for example, for
testing.
Detailed explanation (of the assembly STS 'th).
After assembly and write addresses
at the paper exit in STS; load through
Menu BASIC loader old release project (Note: make sure your old
and new releases coincided total size blocks!). If the starting
address of program or anything else has changed, perform the
following sequence: Download Sector BASIC loader again, by
substituting numbers with ssL sector 1 (boot size) less than
the current, correct the necessary bytes in it, save through
ssS surface, again reducing the number of sector 1, as it was
(because it increased again after load operation).
In any case, the "current sector" in STS'e
now will point to the sector after
BASIC.
Further through ssS from memory one by one
unloaded all code blocks. Non sector-track update is no longer
necessary. Release is ready.
Variation:
Sticking in the memory of all the blocks and beysiksektor
including thereafter.This program as CODE. Next ship directory
through ssL, correct extension to B, and
Start and Length the length of the BASIC loader
then unload the revised directory
(STS as a disc doctor).
Variation with packing:

convenient, but not perfect, the way the multiple bonding
through the STS (in the very variations), in packaged form.
End of explanation.
Such an understandable way is often used and ya.Odnako it
smoothly I'm tired. For a long time I spent on the
simplification of the problem by parts.
1. Set when the program starts from
assembler (without assembly) under the same conditions that
and running compiled program.
2. Save blocks without manual Barge lstva.
3. Packer run without manual instead Invasive.
4. Configure Basic-block automatic ki.
5. Pasting blocks of the program without exiting
in the Commander.
6. Automatically run the collected
program.
Automation, I began only in 1999.
First decided to task 4 of the BASIC-bloke.Poskolku ALASM
allowed him to compile along with the main program, all the
right numbers can be configured at compile time through the
substitution of the tags. The resulting loader was unloaded as
sector. A complete set of variables operating systems that
had to adjust to save BASIC conventional means, I found later.
This proved to be variable 23649, 23651,
23653, 23641 and 23627.
Yes, BASIC as a sector can unload
without these intricacies. However, wisdom
needs while maintaining a DOS window or
appropriate subroutine of the DOS (function point # C # 3D13).
And, unfortunately, these actions are necessary to restore
operating system state at the time of starting the program, the
problem number one. And this not all. Remains to be done CLEAR.
For this serves as a subroutine with a parameter in 7863
BC. By the way, she moves the stack that
important to consider and should not be forgotten. And then
You can debug, and look for a mistake for life
:)
All the questions start BASIC files decided maaalenkaya
subroutine, found BASIL'om and published in the ZX-Guide #, it
seems, 3, or in the AlCoNews, where he wrote on the command
line. This can autostart insert and to download Hrust (Rip), and
Launch collected their program. However,
second if not first:)
Avtosborschik of itself is organized in
source file for tak.Adres RUN (Last ORG
programs) rather than address the very start
the program is installed, for example,
# 5B00, where garbage is placed. The collector is activated
when the program starts, say, with Caps Shift'om. (You can use
conditional compilation, but it is, I think, not better.)
Without the Caps Shift just a debug program is launched.
However, if convenient, It can be done specially for the debug
run any changes navrode Released in ALASM instead of output in
DOS, to taste. In the same branch autobuild program, of course,
should not be changed - it must remain exactly in the form
conceived.
The trouble is that in Hrust'e (which
Rip) buttons to push, however, it is necessary.
The first major packer, officially
published in the sources, was how
we remember, Hrust 2.x. It is this algorithm
I started to use instead of bulky
compressors with an interface. Benefits
Tamed compressor avtosborschike
obvious.
Tamed compressor can be stored and
in the form of a code block, not compiling each
times. After all, the problem was only in the presence of
interface, which is absolutely not necessary,
to pack the unit with the address N of length L in
e M, where L, M and N are known and entered into
in the label.
Automatically save blocks (wrapped) and glue the project
when compared with all passed is quite
prosto.Blago even DOS functions are provided for all correct,
except for gluing monoblokom.Monoblok, alas, have to create
Directory iskusstvenno.Ili change in the number of files, or
changing the length of Basic and free diska/1-go free sector -
while retaining the blocks are not files.
At this decision I am, so to speak, and it remains novilsya.

When I first showed this avtosborschik the people, I had to
make the program "mkace", which itself loads the assembly and
presses the button for the user. Hence the availability control

her routine to intercept the key, too, is in BASIC.

But Hrust2.x, being a relatively good packer (fast, for
example, and short), is packed between relatively weak. Based
on just then write RAR'a engine and parts unpacker RIP
Petrov's novel, I realized its wrapper
specifically for the automobile assembly, called
mRIP. His depaker butt occupies the region
BASIC, which eliminates the need to think a head like that
BASIC should look like. However, Georgia and unpacks this BASIC

Except that to load additional components of the intro (the
very intro download loader mRIP). But for the software programs
that fit into low memory, mRIP good. Have in mind, Pro Tracker

However, through "Intro" - is also possible. A ACE simply must
