>Right, but the problem is that the program is build on a class that needs table buffering to work well. From the moment i change the buffering status this thing starts to act strange. (even when i change it before the index an reset it afther the index)

I uses Table buffering with emptying buffer/RecordBuffer/IndexOn/Tablebuffer change,
and until now i have not found critical issues.

Of course, if you want a change of order with table buffer not empty,
you have to work very more.

RV don't support literal parameters, like:

SELECT * FROM db!sometable ORDER BY &?eOrder

a way can to be, to define the RV on the fly, at runtime.
