I'm total begginer so let's begin =)
for example i want to read specific line from a txt file, how do i do that!?!?!
for example Code:

AssignFile(Somefile, 'somefile.txt');
Reset(Somefile);
// how to read line??? //
Closefile(somefile);

i was trying to findd something on internet, maybe there were correct answers but i didn't understand them... so if anyone knows, HELP ME and with some explanations would be better...

You can use ReadLn() to read a line from a text file. The first ReadLn() reads the first line, second ReadLn() the second, etc.
Alternatively you can create a TStringList object and call its LoadFromFile(). This will store the entire fill into the object. Then you can use the Strings[] property to get the line you want.

Thank you will try it

didn't understand how to use TStringList, so i wrote little code:
AsignFile...
...
repeat
var2:= var2+1;
readln(file, var);
until var1 = var2;
...
that's how it was solved! =)

Here is a slightly better code, which also checks if the file is not empty:

  while not eof(file) do
  begin
    var2 := var2+1
    readln(file, var);
    if var1 = var2 then Break;
  end;

When using the TStringList variation:

var
  FileContents: TStringList;
begin
  FileContents := TStringList.Create;
  FileContents.LoadFromFile('filename.txt');
  // Use Filecontents
  Line := FileContents[var2];
  // until you don't need them
  FileContents.Free;
end;

zibadian Thanks once again!
