tuple_find — Return the indices of all occurrences of a tuple within another tuple.
tuple_find searches Tuple sequentially for all occurrences of the values of the second tuple ToFind and returns the indices in Indices (in relation to the first input tuple Tuple). For example, if Tuple contains the values [3,4,5,6,1,2,3,4,0] and ToFind contains the values [3,4], the output tuple Indices will contain the values [0,6]. If the first tuple does not contain the second tuple as a subtuple, tuple_find returns -1 in Indices. It is allowed to mix strings and numbers in the input tuples.
If either or both of the input tuples are empty, the operator returns an empty tuple.
HDevelop provides an in-line operation for tuple_find, which can be used in an expression in the following syntax:
Indices := find(Tuple, ToFind)
Input tuple to examine.
Input tuple with values to find.
Indices of the occurrences of the values to find in the tuple to examine.
