问题描述
最近，我一直在学习某种汇编语言，我对汇编应用程序.Data段上的DB声明有疑问.
直到现在，我总是这样声明一个字节:
Hi,
Lately I have been Studying some Assembly language, I have a question about the DB Decleration on the .Data Segment of an Assembly Application.
Till Now, I always declared a Byte by doing So:
Number db "Please enter a number : ",0
(名称)db(字符串)，0
今天，我找到了一个具有如下字符串声明的示例:
(Name) db (String), 0
Today, I found an example which had the String Declaration as Follows:
Hello db "Hello World!",13,10, 0
我对13、10有疑问.
谁能指出这些意思.
谢谢

I Have a Question Regarding the 13, 10.
Can anybody point out what these mean.
Thank You,
Andrew Borg
推荐答案
char* Hello = "Hello World!\n";不过，最好将它们声明为助记符，因此您可以使用可读的名称代替数字:
It is a good idea to declare these as mnemonics though, so you can use readable names instead of numbers:
Hello db "Hello World!", AS_CR, AS_LF, 0(我可能不会将AS_NULL用作零，因为它很可能是字符串终止符，而不是一个要显示的字符)
(I probably wouldn''t use AS_NULL for the zero, as it would most likely be a string terminator, rather than a character to display)
