Thanks Helen for taking the time to respond.

I already know about native IBO, but I'm talking about TDataSet IBOQuery, not
IB_Query. Someone already gave me some pointers on using TIB_Column and
OnGetText with the AfterPrepare event.

What I still need is the same ability to dynamically assign OnGetText event to a
non-persistent TField of the IBOQuery.

Any suggestions?
