For some people who need to use the DOS program, a "MS-DOS Mode" similar to Win9X is provided in Windows XP, and now it is called "Command Prompt", which is in "Start / All Programs / Accessories". With it, we can start a multi-program, and provide a command start Start specifically in the DOS state, which launches a separate "command prompt" window to run the specified program or command. If you don't have a parameter, Start will open the second command prompt window. There are many parameters of the start command, the meaning of each parameter is as follows: "Title" Specifies the title displayed in the "Command Prompt" window title bar. / DPATH Specifies the start directory. / i transmit the CMD.exe launch environment to the new command prompt window. / min launched a new minimization "command prompt" window. / MAX starts a new maximized "command prompt" window. / Separate launches 16-bit programs in separate memory space. / Shared launches 16-bit programs in shared memory space. / LOW launches the application at idle priority. / Normal launches the application in general priority. / High starts the app with a high priority. / RealTime launches the application with real-time priority. / ABOVENORMAL launches the application in a manner that exceeds a regular priority. / Belownormal launches the application in a way up to the regular priority. / WAIT launches the application and waits for its end. / b When starting an application, you don't have to open a new command prompt window. The Ctrl C operation will be ignored unless the application enables Ctrl C. Use the Ctrl Break to interrupt the application. In fact, use the start command to start any Windows program, such as you want to start the Notepad (Noteping Program), and if you can't find it in the attachment, type Start NotePad in the beginning of the run menu, Windows XP will open Notepad. .
