Code4bin | Delphi

procedure WriteSimpleBinary; var Data: TBytes; Stream: TMemoryStream; Value: Integer; begin SetLength(Data, 4); Value := 12345; Move(Value, Data[0], 4); // direct memory copy Stream := TMemoryStream.Create; try Stream.Write(Data[0], Length(Data)); Stream.SaveToFile('output.bin'); finally Stream.Free; end; end; In the style, you would encapsulate this into a reusable TBinaryWriter class. 2. Record Casting (The Delphi Superpower) Delphi records can be read/written directly to streams if they are packed and contain only value types.

function ReadBit(ByteValue, Position: Byte): Boolean; begin Result := (ByteValue shr Position) and 1 = 1; end; Let’s create a realistic Code4Bin.pas unit that you can drop into any Delphi project (10.3+ or modern Community Edition). code4bin delphi

uses System.Classes, System.SysUtils;

This is quintessential – moving structural code directly to binary. 3. Endianness Handling A hidden trap: Intel CPUs are little-endian. Network protocols are big-endian. A robust Code4Bin module includes swapping functions: Endianness Handling A hidden trap: Intel CPUs are
