lcPathInZip = "example.dat"

* ------------------------------------------------------------------------
* The AppendNew method is deprecated:

loEntryObj = loZip.AppendNew(lcPathInZip)
IF (loZip.LastMethodSuccess = 0) THEN
    ? loZip.LastErrorText
    RELEASE loZip
    CANCEL
ENDIF

* ...
* ...

RELEASE loEntryObj

* ------------------------------------------------------------------------
* Do the equivalent using AddEmpty.

* Indicate the newly appended entry is not a directory entry.
lnIsDir = 0

lnSuccess = loZip.AddEmpty(lnIsDir,lcPathInZip)
IF (lnSuccess = 0) THEN
    ? loZip.LastErrorText
    RELEASE loZip
    CANCEL
ENDIF

* Do the following if you need the zip entry object for what was just appended.
* The newly appended entry is the last one.

lnIndex = loZip.NumEntries - 1
loZip.EntryAt(lnIndex,loZe)
