As this hasn't popped up before, it's possibly quite recent. Could
you please post the exact version of IBO where you first saw this problem?

entire phrase of the order clause as one string...I believe that was
later fixed....but, until now, your statement would fail to prepare if
you included the keywords.

changes, that the parser doesn't handle that phase quite the way it
did before. The GSG hasn't been updated for a very long time...

Thanks very much Helen.

I'm using IBO 4.6.B. as you advised to some time ago.
I'm not sure if there has been a more recent stable version?
