choose character from string in delphi

To choose a character from a string in Delphi, you can use the CharAt function. Here's an example:

  myString: string;
  myChar: Char;
  myString := 'Hello, World!';
  myChar := myString.CharAt(7);
  // myChar will now contain the character 'W'

In this example, we declare a string variable myString and assign it the value "Hello, World!". We then use the CharAt function to retrieve the character at index 7 (remember that string indexing starts at 1 in Delphi). The resulting character is assigned to the myChar variable.

Note that Delphi strings are 1-based, meaning the first character in a string is at index 1, not 0 like in some other programming languages.
