Hash and Hash Iterator Object Language Elements |
Returns the last value in the underlying hash object.

Hash iterator object

-
rc
-
specifies whether the method succeeded or
failed.
A return code of zero indicates success; a non-zero
value indicates failure. If you do not supply a return code variable for the
method call and the method fails, then an appropriate error message is written
to the log.
-
object
-
specifies the name of the hash iterator
object.
The LAST method returns the last data
item in the hash object. If you use the ordered: 'yes' or ordered: 'ascending' argument tag in the DECLARE statement or _NEW_
operator when you instantiate the hash object, then the data item that is
returned is the one with the 'highest' key (largest numeric value or last
alphabetic character), because the data items are sorted in ascending key-value
order in the hash object. Conversely, if you use the ordered: 'descending' argument tag in the DECLARE statement or _NEW_ operator when you instantiate
the hash object, then the data item that is returned is the one with the 'least'
key (smallest numeric value or first alphabetic character), because the data
items are sorted in descending key-value order in the hash object.
Use the FIRST method to return the first data item in
the hash object.
Note: The LAST method sets the data variable to the
value of the data item so that it is available for use after the method call. ![[cautionend]](../../../../common/63294/HTML/default/images/cautend.gif)
