### Include

#### Synopsis

    Include (set_variable, ordinal_value);

#### Description

Add (join) a single element to a set. ordinal_value must be compatible with the base type of set_variable. Include is equivalent to:

    set_variable := set_variable + [ordinal_value];

If set_variable already contains ordinal_value, nothing happens.

#### Conforming to

`Include` is a Borland Pascal extension.

#### Example

    program IncludeDemo;

    var
      Ch: Char;
      MyCharSet: set of Char;

    begin
      MyCharSet := ['P','N','L'];
      Include (MyCharSet , 'A');  { A, L, N, P }
    end.
