我的vs 6.0 c 的 system(“cls”); 清屏 函数 不能用了 怎么回事？ 谢谢

网友回复:C

网友回复:我之前的编译器用的还好使，可是重装机器后重新下vc就不能用system了，why?
网友回复:报的是什么错误? .

Google之
网友回复:应该是你改了Windows的环境变量。 你找一个正常的电脑，抄回来就行了。
网友回复:错误信息是什么？
把它copy出来
网友回复:没有报错，就是没有清屏，我的环境变量假如有问题的话，为什么我在run->cmd->cls却好使呢？不是系统变量的问题吧？

Process Control Routines

Prototype

int system(const char *command);

int _wsystem(const wchar_t *command);

Description

Issues an operating system command.

system invokes the operating system command processor to execute an operating system command, batch file, or other program named by the string command, from inside an executing C program.

To be located and executed, the program must be in the current directory or in one of the directories listed in the PATH string in the environment.

The COMSPEC environment variable is used to find the command processor program, so it need not be in the current directory.

Return Value

If command is a NULL pointer, system returns nonzero if a command processor is available.

If command is not a NULL pointer, system returns 0 if the command processor was successfully started.

If an error occurred, a -1 is returned and errno is set to one of the following:

ENOENT Path or file function not found
ENOEXEC Exec format error
ENOMEM Not enough memory

system("cls"); //用了中文的引号？
