BDE 5.0 Sybase SQL Links and CS CURSOR ROWS

I've just started looking at Delphi, as a first step I'm
looking at the BDE 5.0 etc.

On the release notes on SQL Links it mentions an additional
parameter that is undocumented for the SQL Links Sybase driver
called CS CURSOR ROWS via which you can set the npo. of internal
rows fetched. Basically, it suggests that by tweaking this
you can perhaps gain some extra speed. But the one thing it omits
is how you actually set this, I can't find it of the BDE admin - am
I missing something?

Cheers Daz.
