This is exactly what I was looking for.  I did a bit of searching and found
the typical values for the first parameter:
ADS_PROPERTY_CLEAR = 1
ADS_PROPERTY_UPDATE = 2
ADS_PROPERTY_APPEND = 3
ADS_PROPERTY_DELETE = 4

<code>
me.set(**details)
</code>

Tim, thanks for the help and the quick response.  I frequently see helpful
responses made by you scattered around the web.  I am fairly certain that I
would be stuck in VBScript if you were not around to help the community.
Cheers,
