Write your reply.

assistant: Hi,
This may be a very silly question but if I don't ask it I won't know :) So
here it is: Is it possible to take a 80x86 assembler code and translate it to
Z80 assmbler code (automatically ofcourse, manually I'm sure it can be done),
and if yes what program would do that for me?

assistant: Hi John,
 I DO realize that docs, is spelled docs, had I intended to spell it as such
 I would of. The DOX reference is just a little hold of over of my C64 days,
 which I kinda liked. (besides, bad form correcting the english anyway :)
 I'm also not assumeing that people are familiar with MASM. It's more of
 a research thing. You download the file and check out the ASM.DOC file and
 it says this is a MASM 3.0 clone.
 Knowing that, one can simply ring around, check, etc for information
 concerning MASM. With any luck, such as in my case, you'll find all the
 documentation you need.
 Yes, granted that's my local library, but surely there must be something
 in yours? If not, one could always order the book itself, but then I guess
 that defeats the purpose of a "free" assembler! :)
 Cheers,

Write your reply.

assistant: SM
 Ahh, I see. I don't think you mentioned that in the beginning, only what
 was DGROUP.
 I answered this already I believe. Why? Well, look at your MODEL line, it
 specifies a C model does it not?
o
 Which is what I just said that this DGROUP shell would work for, using
 old directives, correct? So then, your DGROUP, is simply formed by all
 those above. Just that in small direcives the above DGROUPing is done for
 you my MASM. (rather then typeing it all out)
 Yes I am, but then again what ARE simplified directives? They are just the
 old ones simplified.
 For example this:
 .STACK 1024
 is really the same as say this:
 STACK SEGMENT PARA STACK 'STACK'
        db 1024 DUP(?)
 STACK ENDS
 Well, it would be from the .MODEL wouldn't it not like I just
 mentioned. More importantly, the C type, defining a C program as outlined
 by Microsoft. Which means there a several segments like CONST, BSS, TEXT,
 etc for various parts of the program. Which would be included for you as
 part of that C definition.
 Does that seem reasonable and more helpful? BTW: I don't have MASM or the
 manual anyway. :)

It's no effective CRACK protection, though it is a good COPY protection,
because without cracking the loading routine you are not able to COPY that
disc. For protecting it against CRACKING, you have to apply a CRACK
protection to the loader. That together should make it harder to crack and

Write your reply.

assistant: psst, take a look at the resulting .MAP file after assembly.
DGROUP is the name of a "group" of segments that are refered to seperately in
your source but are linked into a single segment at assemble/link time.
The address of any segment is determined at RUN time. When DOS loads and
executes your program, one of the things it does is look at a "relocation
table" and update values such as these within the memory image of your
program.
For every reference to DGROUP, or @DATA, or any other user defined segment ..
there is a corresponding relocation table entry that points to that
ference.

Write your reply.

assistant: (from the book "PC Interrupts" by Ralf Brown & Jim Kyle)
New executables begin running with the following register values:
AX      = environment segment
BX      = offset of command tail in environment segment
CX      = size of automatic data segment
ES, BP  = 0000h
DS      = automatic data segment
SS:SP   = initial stack
(from the TASM user's guide)
When you load an EXE program, the operating system sets up the registers as
follows:
DS, ES  = PSP segment
CS:IP   = start address
SS:SP   = stack address
I think AX may also be loaded for the second one, which specifies the PSP.
n
the newer executable types as above, the PSP in real mode can be found by
subtracting 0010h from the value of CS.

 Interesting. What version of MASM where those sources coded for? If they're

 So far, all the MASM 3.0 stuff I've thrown at it has worked out fine. With

Well, anything that starts with an F is a floating point instruction.
If it's followed by an I, that means the floating point unit is going to
do an integer operation.  SUB simply means subtract and R means Reverse.
In the floating point unit, you normally specify only one operand, with
the top of the floating point stack being implied as the other operand
(for any instruction that takes two operands; if an instruction needs
only one operand, you normally don't specify it at all.)
Normally, the top of stack is taken as the destination operand, but with
a "reverse" instruction, the top of stack is taken as the source operand
and whatever other operand you specify in the instruction becomes the
destination.
So, this means take the value on top of the floating point stack,
subtract the value at [bp+di] from it, and place the result into memory
at [bp+di], and do an integer subtraction instead of a floating point
subtraction.
    Later,
    Jerry.

and you solved the problem too, thanks for the follow up... i did
aswell after i started playing with a debugger and stepping through
the program...
and the problem was that xor ax, ax... i put it before arge: and as a
result it wasn't 0 after the first pass through the loop... dos wound up
being told to check drive number 2 instead of 0 (and there is no drive
2)...
well, i've done more testing on it (and my version after i fixed the
original problem) and i found a new glitch, or at least it's a
behaviour i don't understand... the 4626 byte image file is invalid, it
should (though i didn't realize this before) be 16962 bytes... if the
floppy drive is not read in any way before the program is executed the
4626 byte image is produced but running a hex editor like norton
diskedit or even just performing dir a: before running the disk backup
program will result in the 16962 byte file being produced (with both our
versions of the program)...
it did when i commented out the ".stack"....
how true... a restoration routine would probably be good too...
