Paul,

[IBO] .. craziness ? After 3 years using IBO, you should know a little
more about these client/server basics !! With single fetching, how can
IBO know the begin or end of the dataset ? What should it return other
than a bof/eof error ??? You really should read some basic tutorial.

The most easy way to solve your problem without any extra coding is:
------------------------------------------------------------------------
* From the Delphi standard component tab place a ActionList on your form.
* doubleclick on the actionlist.
* press "New standard action".
* choose TIB_ActionNext and TIB_ActionPrior.
* assign at least your datasource to the actions datasource property.
* place two standard buttons for Next/Prior on your form.
* Assign the appropriate action to each buttons action property

That´s all you have to do, IBO´s predefined actions do all the rest !
