Use the Fields[] property - just don't instantiate the field objects.

My idea of RAD is that you take what's useful and leave alone what is
not. The "R" in RAD stands for "rapid", not "redundant". To me, the "RAD"
in Delphi is the way I can write bits of reusable code and put them into
libraries to use again and again, the way I can take care of memory in a
totally consistent way, and ESPECIALLY the way I can bypass RAD features
that are no use to me.

Sure, if you want to exploit every noisy thing in Delphi, do it! Nobody is
going to stop you from chewing up all your system resources to save a bit
of coding, if that is your desire. But you don't get butter on both sides
of the bread. Just don't complain when you make your application slow at
doing its real work!
