Informs the index set that it is an identity.

Synopsis

is -the index set

Note: The IS will be considered the identity permanently, even if indices have been changes (for example, with ISGeneralSetIndices()). It's a good idea to only set this property if the IS will not change in the future. To clear this property, use ISClearInfoCache().
