### 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.
