general:

oPcodeR is quite easy to use. Simply enter the instruction and hit -Enter- or
click on -Generate-. (see "SUPPORT.TXT" for supported instructions)

The use of operands is basically the same as in all other similar programs.
Except for one fact: memory operands.
Here, some abbreviations come into play.
Normally it would look something like:
	(instruction) byte ptr [memory],
	e.g. inc byte ptr [00123456]
oPcodeR does support memory operands, but uses single characters instead of
"byte ptr", "word ptr", and "dword ptr".
The appropriate characters are "b" (byte ptr), "w" (word ptr), and "d" (dword
ptr). Besides memory operands do not have brackets.
Therefore the above-mentioned example would be:
	(instruction) b memory,
	e.g. inc b 00123456

Abbreviations for pointers are:
	b - byte ptr
	w - word ptr
	d - dword ptr
	q - qword ptr
	t - tbyte ptr (= 80 bits operand; used with floating-point operations)


Operands containing register combinations as memory addresses are not supported,
e.g. mov eax, [edi+ebx*2].

oPcodeR only processes values up to 32 bits. See #01 for maximum values.
In case you enter a value that is greater than those you may either experience
corrupted results or an exception will be raised.


In the upper left corner of the main window is a button, "menu". Click on it
and you are getting a menu with the following items:
	jump generator   -   generate jumps (jmpu, jmpc, call)
	base converter   -   convert basic number formats (dec, hex, bin, oct)
	read this ...    -   show readme
	exit             -   exit program



* jump generator:

This is useful for generating jump opcodes. Direct jumps are supported only.
That means instructions like "jmp eip" or "call ebx" are resulting in errors.
Jumps to memory addresses, e.g. "call word ptr [00400322]", are not accepted
either. To check such calls use the default input window.


* base converter:

This lets you convert the basic number formats (decimal, binary, hexadecimal,
octal) into one another.


* read this:

This will display the readme file.


* exit:

what it says ...




#01 ..... max. values:

bin - 11111111111111111111111111111111
dec - 4294967295
hex - 0FFFFFFFF
oct - 7777777777


#02 ..... fonts

oPcodeR comes with the true-type font Andale Mono(TM). I recommend you install this
font. It won't keep the program from running if it is not installed, but it looks
a little better.
