Here, first explain what is DOS?
disc operating system (DOS)
At present, our commonly used operating systems are windows 9x/Me, nt, 2000 and so on. , are all visual interfaces. Before these systems, the operating system used by people was DOS system. At present, dos system is not used by many people, but there are still DOS commands in the windows system we use. Most DOS commands have become a visual interface in Windows, but some advanced DOS commands still need to be executed in DOS environment. Therefore, it is necessary for us to learn the command line to skillfully operate the Windows system.
Different operating systems use different commands to enter the command line interface.
Type the mand command in the running program in the start menu of Win9x/Me to enter the command line interface.
Type cmd command in the running program in the start menu of Win2000/NT to enter the command line interface.
The functions of the gallbladder, such as installing the system must be completed under DOS and formatted ... and so on. ..
Lots and lots.
Question 2: What do you mean by running from the command line? Click start-> run (or WINDOWS logo key +R), then enter dotNetFx35setup.exe/lang: enu in the prompt box that opens and confirm.
Question 3: What does cd mean in the command line? Change the current directory
1. Function: Change the current directory.
2. Type: Internal command
3. Format: cd[ drive letter:] [path name] [subdirectory name]

(1) If the path and subdirectory name are omitted, the current directory will be displayed;
(2) If "cd" format is adopted, the root directory is returned;
(3) If the format is "cd ..", it will return to the previous directory.
Example: (1) enters the user subdirectory; (2) returning from the user subdirectory to the subdirectory; (3) Return to the root directory.
C: \ > CD fox \ user (enter the user subdirectory under the fox subdirectory)

Question What is the command prompt of DOS? It seems that only old birds have been exposed to DOS, and computer novices have only a little knowledge of DOS. It used to occupy most areas of personal computer operating system, and it can be seen on most computers in the world. Because DOS system does not need a very powerful hardware system to support it, it can be used from enterprise users to home users. Although it is not an excellent operating system at present, the backward compatibility of Microsoft software determines that when Windows has problems, it often needs to be solved under DOS, especially for computer enthusiasts and friends who usually like DIY. Therefore, it is necessary to understand and learn DOS. begin
There are two common ways to start the command prompt: 1: Start \ All Programs \ Accessories \ Command Prompt.
2: Start \ Run \ Command
Basic commands-DOS commands, regardless of case, total about 100 (including text editing, virus killing, configuration files, batch processing, etc. ). The following details several commonly used DOS commands.
1 directory
Dir is the abbreviation of English word directory, which is mainly used to display files and subdirectories under a directory.
Function: Display the information of files and subdirectories in the specified disk and directory, including the volume label of the disk where the files and subdirectories are located, the names of the files and subdirectories, the size of each file, the date and time when the files and subdirectories were established, the number of file subdirectories, the total number of bytes occupied and the total remaining space on the disk.
Format: dir[c:] [path] [file name] [. ext] [/o] [/s] [/p] [/w] [/a]
Description: dir is one of the most commonly used DOS commands. Slash indicates that the content behind is a parameter. The most commonly used parameters of DOS parameters are as follows: The meaning of common parameters of dir command.
Meaning of parameters
/p When the display information is full, pause the display, and press any key to display the next screen /o classified display. O can be followed by letters with different meanings.
/w only displays the file name directory name, with five file names per line. That is, wide line display
/s displays all directory files of directories and subdirectories.
/a Displays all files in the directory (including system files and hidden files).
Example: View and display all files in the C:\ folder. At the DOS command prompt, enter dir c:\ /a /p, first enter the dir command with spaces, then enter the directory name c:\ to be viewed, then enter the parameters of this command /a (display all files) and /p (pause display), and finally press enter to execute the command. Tip: To get Help under DOS, you can directly enter Help to view all the help, or you can command/? View help for this command. 2 CDs
Cd is the abbreviation of English change directory, which is used to change the location of the directory.
Function: change or display the current directory
Format: CD[C:][ path]
Note: There are two paths: absolute path and relative path. If there is only one cd with no parameters, only the current path will be displayed. Note: There must be two "special directories" in the subdirectory, namely "."and "..", where one point represents the current directory and two points represent the parent directory. From a simple and practical point of view, as long as you learn to enter step by step (a directory name under cd) and exit step by step (cd), you can solve all the problems ...). Of course, you can also use the absolute path method.
For example, enter the Windows directory at the root of C: disk. 3 md
Md is the abbreviation of English make directory, which is used to create an empty directory.
Function: Create a subdirectory.
Format: MD[C:] path
Example: use md to create a directory named kingstone in the C: root directory ... >>
Question 6: What is *? * What does it mean in the Linux command? All files are *. * institutional documents, such as AAA.txt, can't be done without a suffix.
* Wildcards represent the number and type of indefinite characters. Both Chinese and English numbers are acceptable.
Only that decimal point is necessary.
Question 7: What is the instruction? An instruction is a command that instructs a computer to perform an operation. It consists of a string of binary numbers.
An instruction usually consists of two parts: operation code+address code.
Opcode: indicates the type or nature of the operation to be completed by the instruction, such as fetching data, adding data or outputting data.
Address code: indicates the content of the operation object or the address of the storage unit.
Macro instruction:
Macro instructions are pseudo instructions in assembly language programs.
Its format is
[macro instruction name] macro [formal parameter]
……
code segment
……
ENDM
Use "formal parameters" to substitute some given names or values (arguments) when quoting macro instructions. The use of formal parameters brings great flexibility to macro instructions.
Macro call format
[Macro Instruction Name] [Actual Parameter]
The real parameter item will replace the formal parameter in the macro instruction accordingly. If the formal parameter is a label, the argument should also be a label in the macro call, and the argument should be unique. If the macro definition has its own label, the assembler will automatically change the label to a unique label when calling the macro.
Pseudo-instruction:
Pseudo-instructions (pseudo-operations) are not executed by the computer while the program is running like machine instructions. An operation handled by the assembler in the process of assembling the source program. It can complete the functions of processor selection, program mode definition, data definition, storage area allocation, program end indication and so on. Pseudoinstructions do not generate code at compile time. The compiled pseudo instruction does not exist.
