Hello again,

thanks for all responses. I didn't sleep very well last night because I
later realized that perhaps in my previous posting I let my frustrations out
too much and was afraid they would evoke some hard feelings. I'm very glad
this has not happened. I can see that this community consists of some
brilliant people and I sure wish you all the best of luck.

- preparing:
TDataSet itself is an abstract ancestor class, there are Prepare methods in
descendants like TQuery or TIBDataSet. I tend to use parameterized queries a
lot and have noticed the performance improvement with Prepare. From your
postings I have the impression that I've been missing something essential
all the time.

- searching:
I presume you mean incremental searching within a result set of a query.
I've always done this using parameterized queries, and I thought I was doing
it the right way.

Here I'm sure I must be missing something. Let me conclude here with a
simple fact that I need to do some studying before I can discuss these
points.

Thanks everybody for your comments, and your generous treatment of a
(somewhat confused) newcomer.
