Hi Dennis

you could use CURSORSETPROP properties like

FetchAsNeeded
or
FetchSize

If you are working with CA then there are equivalent properties available.

Debugging is twice as hard as writing the code in the first place.
Therefore, if you write the code as cleverly as possible, you are,
by definition, not smart enough to debug it.
