逗号分隔类型声明致命错误“=”预期但“，”发现自由帕斯卡
我正在使用 Free Pascal 和 VS Code 学习 Pascal。简单类型声明会发生编译错误。我看过教程和书籍，语法似乎不错。如果我删除“天”，使其成为一个单一的声明，它就可以正常工作。我缺少什么？提前致谢。
program Test;
uses crt;
type
days, age = integer; {Fatal: Syntax error, "=" expected but "," found}
var
myAge: age;
begin
myAge := 5;
writeln(myAge);
end.
I am learning Pascal using Free Pascal and VS Code. A compilation error occurs from a simple type declaration. I have looked at tutorials and books and the syntax seems good. If I remove "days," making it a single declaration it works fine. What am I missing? Thanks in advance.
program Test;
uses crt;
type
days, age = integer; {Fatal: Syntax error, "=" expected but "," found}
var
myAge: age;
begin
myAge := 5;
writeln(myAge);
end.

您的语法错误，请参阅 开头的语法图Free Pascal 语言参考，第 3 章类型：
和 第 3.8 章类型别名：
如您所见，Free Pascal 的语法
Type块中的类型别名为：=（等号），后跟类型（可选，声明新类型而不是别名）;（分号）因此，正确的表达你想要的东西的方式是这样的：
嗯，正如您从您所使用的语言的文档中看到的那样，事实并非如此。
您可能没有查看 文档 免费 Pascal 但其他一些语言。
Your syntax is wrong, see the syntax diagram at the beginning of the Free Pascal Language Reference, Chapter 3 Types:
and Chapter 3.8 Type aliases:
As you can see, the syntax for a Free Pascal type alias in a
Typeblock is:=(equals sign) followed bytype(optional, to declare a new type instead of an alias);(semicolon)So, the correct way to express what you want would be something like this:
Well, as you can see from the documentation of the language you are writing in, it isn't.
You probably did not look at the documentation of Free Pascal but some other language.
