Why most Delphi examples use FillChar() to initialize records?

Question

I just wondered, why most Delphi examples use FillChar() to initialize records.

type
  TFoo = record
    i: Integer;
    s: string; // not safe in record, b         


        

Answer 1

Here is a better way to initialize stuff without using FillChar:

Record in record (Cannot initialize)
How to initialize a static array?
