I advice using FreeAndNil A always, without exceptions, and never to call directly the Free method or Destroy destructor. Transcendental functions are evaluated using the standard polynomials found in math books.

Control flow

This can be done by redefining the identifier in your new unit. TObject ; procedure btnTestClick Sender: If this is the first. There are times when you deal with large packages and you can't easily retain compatibility to different versions of the packages themselves.

If any phone field is empty, it changes that field to "": This prints the data contained in the numeric variable created above: RFO Basic is easy enough for absolute beginners and average computer users to operate immediately, but powerful enough for a variety of professional uses.

Calling inherited method Within a method implementation, if you call another method, then by default you call the method of your own class.

Analogous rule is for or expression. If the iteration is the last one in the loop, the effect is to terminate the entire loop early. More Program Flow Structures 6.
