* The FetchChunk method is deprecated:

IF (loImap.LastMethodSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loImap

    RELEASE loFetchedSet
    CANCEL
ENDIF

RELEASE loBundleObj

* ------------------------------------------------------------------------
* Do the equivalent using FetchRange.
* Your application creates a new, empty EmailBundle object which is passed 
* in the last argument and filled upon success.
