How to use debug.exe

debug.exe usage introduction: 1. You need to open the command prompt window. In Windows systems, you can open the command prompt window by pressing the Win R key combination and then entering "cmd"; 2. In the command prompt window, enter the "debug" command and press the Enter key to start debug.exe.

debug.exe is a commonly used debugging tool in Windows operating systems. It helps developers diagnose and fix bugs in their programs. This article will introduce the basic usage of debug.exe and some common debugging techniques.

First, to use debug.exe, you need to open a command prompt window. In Windows, you can open the command prompt window by pressing the Win R key combination and then typing "cmd". In the command prompt window, enter the "debug" command and press the Enter key to start debug.exe.

Once debug.exe starts, you will see a "-" symbol, which indicates that you have entered debug mode. In debug mode, you can enter a series of commands to perform different debugging operations.

The following are some commonly used debug.exe commands:

1. a (assemble): used to write assembly instructions into memory. For example, entering "a 100" will write an assembly instruction at memory address 100.

2. d (dump): used to view the contents of memory. For example, entering "d 100" will display hexadecimal data starting at memory address 100.

3. e (enter): used to modify the contents in memory. For example, entering "e 100 90" will modify the data at memory address 100 to 90.

4. g (go): used to run the program. For example, entering "g" will start executing the program.

5. r (register): used to view and modify the value of the register. For example, entering "r" will display the current register value.

6. t (trace): used to execute the program one by one and display the execution results of each instruction.

In addition to the above commands, debug.exe also provides other commands and debugging functions, such as setting breakpoints, single-step debugging, etc. You can view the help document of debug.exe by entering the "?" command to learn more commands and usage.

It should be noted that debug.exe is a relatively old debugging tool, its functions are relatively limited, and it does not support debugging newer programming languages ​​and frameworks. In modern development environments, more powerful and easy-to-use integrated development environments (IDEs) are usually used for debugging operations.

To sum up, debug.exe is a command line tool for debugging programs. By entering a series of commands, you can view and modify the contents of memory and registers, execute programs, and perform other debugging operations in debug mode. However, due to the limitations of its functionality, debug.exe is relatively rarely used in modern development environments.
