Operator Reference
tuple_sort_index (Operator)
tuple_sort_index — Sort the elements of a tuple and return the indices of the sorted tuple.
Signature
Description
tuple_sort_index sorts all elements of Tuple in
ascending order and returns the indices of the elements of the
sorted tuple (in relation to the input tuple Tuple) with
Indices. As a precondition the single elements of
Tuple must be comparable. Thus, Tuple must
either exclusively consist of strings or it must only contain
(integer or floating point) numbers. In the latter case integers
and floating point numbers may be mixed.
Exception: Empty input tuple
If the input tuple is empty, the operator returns an empty tuple.
HDevelop In-line Operation

which can be used in an expression in the following syntax:
