It's question. There are lot of links to FETCH in doc, and we support from
FETCH direction only subset. It needs at least notice in documentation. When
I testeid MOVE I found an form
MOVE FORWARD 10 ... more natural than MOVE RELATIVE 10 and if we support
MOVE FORWARD ... then is logic support MOVE FORWARD n ,
else FORWARD, BACKWARD are nonstandard and MOVE statement too.
