Would you mind telling me how to read a specified line of text from a text

eg, what should I use if I want to read the 4th line only, but not the 5th
and the 3rd?
Can Readln do this?
Thanks in advance.

var
TempList: Tstrings;

for index:=0 to templist.count-1 do {enable to process line

begin
if index=4 then main.Ename.text :=templist[index];
end;
end;
finally
TempList.Free;
END;
