Ordinal types helpers are available  for Delphi XE4+.

Helpers (from SysUtils unit) are available for the following types:

•string

•single

•double

•integer

 

For example, you can write

 
ShowMessage('abc'.ToUpper());
s := 'test';
s1 := s.substring(1, 2);

 

Overloaded helper methods

 

Scripter can distinct between overloaded helper methods with different number of parameters.

For example, TStringHelper has two Substring methods:

 

    function Substring(StartIndex: Integer): string; overload;
    function Substring(StartIndex: Integer; Length: Integer): string; overload;

 

You can use both:

 

a.SubString(1) and a.SubString(1, 3)
