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.
