subSequence ( startIndex : Integer, endIndex : Integer ) : Sequence(T)

Returns a Sequence containing all elements of self between the positions 'startIndex' and 'endIndex'.

Expression	Result
Sequence{'a', 'b', 'c', 'd'}->subSequence(2, 3)	Sequence{'b', 'c'}
Sequence{'a', 'b', 'c', 'd'}->subSequence(4, 4)	Sequence{'d'}

Returns a smaller collection from start to stop.

subSequence(<start>, <stop>)

Please note that the index number is 1-based.

Example:

Sequence{1..20}->subSequence(10,15)

The expression above will return numbers 10, 11, 12, 13, 14, and 15.

If you supply index values outside the source collection, the result collection will be empty.

Note: Both startIndex and endIndex are inclusive - the element at endIndex is included in the result.

Examples:Single Element Extraction

Sequence{1, 2, 3, 4}->subSequence(3, 3)

Result:

Sequence{3}

When startIndex equals endIndex, it returns a sequence with that single element. Empty Collection

Sequence{}->subSequence(1, 5)

Result:

Sequence{} (empty)

Out of Bounds - Beyond End

Sequence{1, 2, 3}->subSequence(5, 10)

Result:

Sequence{} (empty)

When startIndex is beyond collection size, returns an empty sequence
