| in | member of a set |
| Syntax | in
|
| Description | The in operator determines if an element is in a set.
|
| Example |
type rankSet : set of 0 .. 10
var rankings : rankSet := rankSet ( 0 ) % The set {0}
…
if 5 in rankings then … % Is 5 in the rankings set?
|
| Description | The not in operator is exactly the opposite of in. For example, 7 not in rankings means the same as not (7 in rankings). The element is required to be in the set's index type. In the above example this is satisfied because element 5 is in the index type 0 .. 10. The keyword in is also used in lists such as import lists. See import list.
