Exclude (set_variable, ordinal_value);
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.
Exclude is a Borland Pascal extension.
program ExcludeDemo; var Ch: Char; MyCharSet: set of Char; begin MyCharSet := ['P', 'N', 'L']; Exclude (MyCharSet , 'N') { L, P } end.
