Node:Include, Next:Index, Previous:Inc, Up:Reference
Include (set_variable, ordinal_value);
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.
Include
is a Borland Pascal extension.
program IncludeDemo; var Ch: Char; MyCharSet: set of Char; begin MyCharSet := ['P','N','L']; Include (MyCharSet , 'A'); { A, L, N, P } end.
