/* Abstract datatype Set for Alan interpreter
|
|
|
|
A set is implemented as a struct holding a size and a
|
|
dynamically allocated array of members. Members can be
|
|
integers or instance numbers. Attributes of Set type is
|
|
allocated and the pointer to it is used as the attribute
|
|
value. As members are only references, clearing a set can
|
|
simply be done by setting the size to zero.
