DOS ain't dead

32-bits dos binaries on 64-bit windows (Users)

It is probably already known, but just to make sure here an observation I just made:

On my vista/64 workstation, I was decrunching some old dos archives, and these are compressed using the "quantum" (.q) compressor. The archive is available on garbo.

The archive contains two programs. A dos program, and a windows compressor I had some hopes for. The windows program (QWIN, NE, so older win16) failed, and just to be sure I ran the dos version, and it RAN.

File identifies them as
32RTM.EXE: MS-DOS executable, MZ for MS-DOS
DPMI32VM.OVL: MS-DOS executable, MZ for MS-DOS
PAQ.EXE: PE32 executable for MS-DOS, 32rtm DOS extender Intel 80386 32-bit
QUANTUM.DOC: ASCII English text, with CRLF line terminators
QWIN.EXE: MS-DOS executable, NE for MS Windows 3.x
READ.ME: ASCII English text, with CRLF line terminators
UNPAQ.EXE: PE32 executable for MS-DOS, 32rtm DOS extender Intel 80386 32-bit
WINDPMI.386: MS-DOS executable, LE executable for MS Windows (VxD)

So they are PE32, but for dos, probably of Borland (C++?) origin, and they run on win64.
