  Description
 
    The IN operator is a QuickPascal operator that tests for the
    presence of an element in a SET. For example,
 
       TYPE
           vacation_days = ( sep4, oct31, dec25, may29, may30, jul4 );
       VAR
           summer_vacation : SET OF vacation_days;
           today : vacation_days;
       BEGIN
           summer_vacation := [ may29, may30, jul4 ];
           today := jul4;
           IF today IN summer_vacation THEN
               Writeln( 'Surf''s up!' );
       END.
