Reading and recording in pascal

[Bogopo]

Hello. I'm here for the first time, so if you're not, you're right.

How can a reading from a file be implemented if the data recording format is not known, i.e. it is not clear how it is written. For example, there's a file, there's a matrix in it.

I don't know how to read it to keep the format of the recording, and I'll put it in a new file. If possible, with an example of such a program.

Thank you for the answer.

Complete.

Well, I asked for opportunities... I can give you the code, but he won't give anything, I just don't know how to do it, so I asked.

//считывание
reset(f);
for i := 1 to n do
for j := 1 to n do
    read(f,x[i,j]);
close(f);
writeln ('матрица, считанная из файла');
for i := 1 to n do
    begin
         for j := 1 to n do
             write(x[i,j]:7:2);
         writeln;
    end;

If the record is like you said,

reset(f);
for i := 1 to n do
begin
  for j := 1 to n do
    write(f, x[i,j]:7:2);
  writeln(f);
end;
close(f);

The reading shall be:

reset(f);
for i := 1 to n do
begin
  for j := 1 to n do
    read(f, x[i,j]);
  readln(f);  
end;
close(f);
