A self-printing machine code program that writes itself to standard output when executed in a DOS environment. It can be tested in a Unix/Linux system with DOSBox or in an actual MS-DOS 6.22 system or Windows 98 system. The program uses x86 machine code and DOS services to write its own bytes. There is a discussion on the definition of a quine and the differences between machine code quines and other quines. The program can also be modified to avoid reading its own bytes and still print itself.
