Using bit tests, you can easily test for specific flags on a flag variable.
使用位测试，可以容易地测试标志变量上的特定标志。
Note the use of the w: prefix, which means that the flag variable is always local to the current window.
注意使用了w：作为前缀，这表示标记变量对于当前窗口来说始终是本地变量。
After loading the Properties object, you close the input stream, and then set your Boolean flag variable (init) value to true, demarcating that the AddressStore object has been initialized.
在加载properties对象之后，关闭输入流，然后设置布尔型标志变量(init)值为true，确定AddressStore对象已经被初始化。
Also notice that you set a flag (the Boolean variable done) to identify when you reach the end of the content that you are interested in.
还需注意，您设置了一个标记(布尔变量done)来确定何时到达感兴趣内容的结束部分。
If the flag takes an argument, the argument is stored in the global variable optarg.
如果此标记带有参数，则参数存储在全局变量optarg中。
To set a variable from the command line when invoking the rundsjob executable file, you must pass the -v flag along with the variable name and value that you want to set it to.
在激发rundsjob可执行文件时，为了从命令行设置一个变量，您必须通过带有变量名以及想要设置值的-v标记。
