i need to write a program.
Source contains a number of strings, each on a seperate line. Read the
strings one at a time printing them to the screen until contained in finish is
read or the end of the file is reached. Write to the screen a message stating
which occured first. The strings are to be considered case sensitive.

i can read the data until the end of file if found, but after that im stuck.. any ideas???

do you mean show the result of the file
you should make an output file, or memo if you would like

assign ( ...... )   //  if you would like to create an output file
rewrite( ..... )   // to make it ready for writing result

or
memo1.text :=  ........


anyway, you said idea, if you would like the code i can write it.

is this what you meant !?

Hi,

program Project1;
{$APPTYPE CONSOLE}
uses
  SysUtils;

var
  f: textfile;
  fname: string;
  EndLine: string;
  line: string;
begin
  // enter some data
  Write('Enter filename:');
  Readln(fname);
  Write('Enter stop line (case sensitive):');
  Readln(EndLine);
  // open the file
  if FileExists(fname) then begin
    Assign(f, fname);
    Reset(f);
    while not EOF(F) do begin
      Readln(f, line);
      Writeln(line);
      if line = EndLine then begin
        Writeln('Stop string has been found');
        break;
      end;
    end;
    if EOF(f) then Writeln('End of file has been reached');
    CloseFile(f);
  end else begin
    Writeln('File does not exist');
  end;
end.
