Record zum Teil als Konstante und Variable?

[TiGü]

Ja.

Delphi-Quellcode:

program Project1;

{$APPTYPE CONSOLE}

{$R *.res}


uses
  System.SysUtils;

type
  TmyRecord = record
  var
    String_1: String;
    String_2: String;

  const
    Boolean1: Boolean = True;
    Boolean2: Boolean = False;
    Boolean3: Boolean = True;
  end;

var
  FooBar: TmyRecord;

begin
  try
    FooBar.String_1 := 'Hello';
    FooBar.String_2 := 'World!';
    Writeln(FooBar.String_1, ' ', FooBar.String_2, ' ', FooBar.Boolean1, ' ', FooBar.Boolean2, ' ', FooBar.Boolean3);
  except
    on E: Exception do
      Writeln(E.ClassName, ': ', E.Message);
  end;
  Readln;

end.
