“标签”如何定义？关键字在 MASM 中起作用吗？
这段汇编代码有什么作用？
someName label word
dw 8 dup(0)
标签如何工作？
What does this assembler code do?
someName label word
dw 8 dup(0)
How does label work?

通常，
label为后面的代码/数据创建一个符号名称，并为其分配一个类型。它类似于定义具有给定名称和类型/大小的变量。但它实际上并没有为其分配空间。它可用于创建变量的别名。Typically
labelcreates a symbolic name for the code/data that follows and also assigns it a type. It's similar to defining a variable with given name and type/size. But it does not actually allocate space for it. It can be used to create aliases to variables.尽管您缺乏有关您正在使用哪个汇编器的详细信息，但我可以猜测一下。
someName label word语句将当前地址（word类型）分配给someName。这意味着稍后在程序中，您可以使用标签someName而不是特定地址。dw语句保留一些word类型的空间。我不完全确定8dup(0)的含义，但它可能是 8 个字（16 个字节）的空间。Despite your lack of details about which assembler you are using, I can take a guess.
The
someName label wordstatement assigns the current address (of typeword) tosomeName. This means that later in the program, you can use the labelsomeNameinstead of a specific address.The
dwstatement reserves some amount of space of typeword. I'm not entirely certain what the8dup(0)means, but it might be 8 words (16 bytes) of space.标签可以放置在语句的开头。在汇编期间，标签被分配活动位置计数器的当前值并用作指令操作数。标签有两种类型：符号标签和数字标签。
A label can be placed at the beginning of a statement. During assembly, the label is assigned the current value of the active location counter and serves as an instruction operand. There are two types of lables: symbolic and numeric.
标签只是代码中特定位置或特定内存地址的名称。通过使用标签而不是实际地址，您的代码可以更容易维护，因为当您添加代码和移动代码时标签不需要更改。编译器将其编译为下面的实际地址。
A label is just a name for a specific location in your code or a specific memory address. By using labels instead of actual addresses, your code can be maintained much more easy because the labels do not need to change when you add code and move around code. The compiler compiles it to actual addresses underneath.
