### Exclude

#### Synopsis

         Exclude (set_variable, ordinal_value);

#### Description

Remove (subtract) a single element from a set. ordinal_value must be compatible with the base type of set_variable. Exclude is equivalent to:

         set_variable := set_variable - [ordinal_value];

If set_variable does not contain ordinal_value, nothing happens.

#### Conforming to

`Exclude` is a Borland Pascal extension.

#### Example

         program ExcludeDemo;

         var
           Ch: Char;
           MyCharSet: set of Char;

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