Example

var
  a: array[1..5] of string;
  b: TStringArray;
  c: Integer;
  d: Byte;
begin
  SetLength(b, 5);
  WriteLn('The lower-bound of static array with range 1..5 is ' + IntToStr(Low(a)));
  WriteLn('The lower-bound of a dynamic array with length 5 is ' + IntToStr(Low(b)));
  WriteLn('The lower-bound of an integer is ' + IntToStr(Low(c)));
  WriteLn('The lower-bound of a byte is ' + IntToStr(Low(d)));
end.

Output:

The lower-bound of static array with range 1..5 is 1
