* The FetchByMsgnum method is deprecated:

loEmailObj = loMailman.FetchByMsgnum(lnMsgnum)
IF (loMailman.LastMethodSuccess = 0) THEN
    ? loMailman.LastErrorText
    RELEASE loMailman
    CANCEL
ENDIF

RELEASE loEmailObj

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

lnHeaderOnly = 0
* Irrelevant because we are not downloading headers-only.
