Include procedure

Include element in set if it was not yet present.

Declaration

pascal

procedure Include(var S: TSetType; E: TSetElement)

Include includes E in the set S if it is not yet part of the set. E should be of the same type as the base type of the set S.

Thus, the two following statements do the same thing:

S:=S+[E];
Include(S,E);

For an example, see Exclude

If the type of the element E is not equal to the base type of the set S, the compiler will generate an error.
