[Gambas-user] Result object, again

[tobias]

good evening all,
i have another question about my eternal punishment: the result object :-)
caveat answered to a former question about results in general:

my question now is, how the result works behind the scenes, is there a 
counter (result.index?) that tells a layer (the driver?) which record is 
to be given back?

regards,
tobi
