IndexesOf

IndexesOf(a)

Returns a list of handles to the indexes of array «a». It is different from IndexNames(a), which returns the identifiers of the indexes as text values instead of handles.

If «X» has an implicit index (an index without a name), the first element of the output list is null, rather than a handle.

If the array has more than one local index with the same identifier, you can use IndexesOf(a) to identify each index safely because each handle unambiguously refers to the corresponding index, where IndexNames(a) would return the identifiers as identical and therefore ambiguous text values.

Syntax:

IndexesOf(a: Array)

Example

IndexNames(Car_prices) → [Car_types, Year]
