fungsi split di delphi

function split(input: string; schar: Char; s: Integer): string;
var
  c: array of Integer;
  b, t: Integer;
begin
  Dec(s, 2);  // for compatibility with very old & slow split function
  t := 0;     // variable T needs to be initialized...
  setlength(c, Length(input));
  for b := 0 to pred(High(c)) do 
  begin
    c[b + 1] := posex(schar, input, succ(c[b]));
    // BREAK LOOP if posex looped (position before previous)
    // or wanted position reached..
    if (c[b + 1] < c[b]) or (s < t) then break 
    else 
      Inc(t);
  end;
  Result := Copy(input, succ(c[s]), pred(c[s + 1] - c[s]));
end;
