Im reading the output from a serial port, it has an event whenever a new line is reached
so the output is buffored per line. the output looks something like

----- somedata some data
     some data
     some data
     some data
------ new data  new
     new  new
     new
     new
     new
    ldkslsdjf

the sequence starts with -------, now I want to have a buffor where I oneventdata
it would add to the string I have the new data then phrase it looking for ------ the new sequence if there is one then the the thing would get processed. Now I tried looking for a split function that would allow the delimeter to be another string but couldnt find one. Can anyone help me?

Try something like:

I:=pos('-- ',inputdata);
if I>0 then begin
  leftside:=copy(inputdata,1,I+2);
  rightside:=copy(inputdata,I+3,255);  // everything after the "-- "
end;

hi,

//this simple function, does what you need
//it returns the first part as result, and shorten the given string
//for next item simple call again
//if there are no items, then the given string becomes empty
function SplitStr(Var AString : String; ADelim : String) : String;
var APos : Integer;
begin
  Result := '';
  APos := Pos(ADelim,AString);
  if APos > 0 then
  begin
    Result := Copy(AString,1,APos-1);
    AString := copy(Astring,APos+length(Adelim),MaxLongInt);
  end
  else
  begin
    Result := AString;
    AString := '';
  end;
end;

//a usage sample
procedure TForm1.Button1Click(Sender: TObject);
var s : String;
begin
 ListBox1.Clear;
 s := edit1.text;
 while s <> '' do
   listbox1.items.add(SplitStr(s,edit2.text));
end;
