Brief introduction
GLC (Glog Cleaner) is the Go language written glog log cleanup class library, Glog is developed by Google, an application-level log framework, providing log grading, file segmentation and other functions, but does not provide log cleanup function, with

[0] Indicates the offset address length, the segment address is default in BS,
However [0] in debug is not the same as in ASM, [0] in ASM after ML will become the value of 0
To solve MOV ax,[1] after AXM compiled into MOV ax,1; can be written mov ax,ds:[1]
Four kinds: mov Al,[0];mov al,ds:[0];mov Al,[bx];mov DS:[BX]

MOV Ax,[0] put an internal deposit element to register AX, memory unit length 2 bytes, offset address 0, segment address DSMOV Al,[0] put an internal deposit element to register AL, memory unit length 1 bytes, offset address 0, segment address DSSo: To describe a memory unit, you need 1.ds and offset address 2. Memory Unit length[BX] also represents a memory unit, offset address in the register BX justWe us
This chapter mainly describes what is [BX] and loop (loop) instruction how to use, loop and [BX] how to combine, what the paragraph prefix is what ghosts, and how to use the paragraph prefix. 1, [BX] concept [BX] and [0] similar, [0] indicates that the memory unit offset address is 0.

Jump instruction is used to implement the program flow jump, in the ARM program there are two ways to achieve the program flow jump:
(1) use special jump instructions.
(2) write the jump address value directly to the program counter PC.
By writing the jump address value to the program counter PC, you can achieve any jump in the 4GB address space, and use it together before jumping

MoV Al, [1]
In debug, data in BS: 1 is assigned to Al, but data in BS: 1 is not assigned to Al in MASM, instead, [1] is considered to be 1 assigned to Al.
If you want to implement mov Al, [1] In debug, you need [BX] In MAS

A middle school student asked me how to find the root of the quadratic equation of one yuan over the past few days. I was so stupid that I didn't know where to start. At that time, I remember that I could never remember the formula, during the examination, it took a lot of time to calculate the formula. The formula calculated from the results is often less than the plus or minus sign. Calculate the formula again this time,
As a result, the student said that this formula was very familiar and fou
[BX] and [0] somewhat similar, [0] represents a memory unit, its offset address is 0, the same [BX] also represents a memory unit, its offset address in BX.Loop, the English word "loop" has a circular meaning, obviously this instruction is related to the loop.We agree that the symbol idata represents a constant, one thing to note here is that it is not possible to send a idata data directly into the segment

There are 8 General registers, which can be divided into two groups. One is the data register (4), the other is the pointer register and the address register (4 ). as the name suggests, general-purpose registers are those that you can use as needed. modifying their values usually does not h

Sidi is a register with similar functions between 8086cpu and BX. Sidi cannot be divided into two 8-bit registers.
The following three sets of commands implement the same functions:
(1) mov BX, 0
MoV ax, [BX]
(2) mov Si, 0
MoV ax, [Si]
(3) mov Di, 0

The following three sets of commands also implement the same function:
