初学者（文件类型）

[zhucezhennan2008]

type
student=record
mytextfile=file of student;
num:integer;
name:string;
age:byte;
sex:boolean;
birthplace:string;
end;

var
mytextfile:file of student;
begin
assignfile(mytextfile,'D:\myfile\file.txt');
Closefile(mytextfile);
end.


mytextfile=file of student; 这有什么问题？

[taste品味]

type
TStudent = record
num :integer;
name :string;
age :byte;
sex :boolean;
birthplace:string;
end;

不用那句

[panrongzeng]

mytextfile=file of student;写这句你想搞什么类型？
没见过这种写法的

[zhucezhennan2008]

type
TStudent = record
num :integer;
name :string;
age :byte;
sex :boolean;
birthplace:string;
end;

不写那句
但到var
mytextfile:file of student;
会报错

类型文件不能包括长字符

[zhucezhennan2008]

type
student=record
mytextfile=file of student;
num:integer;
name:string[10];
age:byte;
sex:boolean;
birthplace:string[20];
end;

var
mytextfile:file of student;
begin
assignfile(mytextfile,'D:\myfile\file.txt');
Closefile(mytextfile);
end.

着就可以了
为什么string[10] 要把占的字节数标出了呢？
