Source code of .obj capable assembler?

    I, unfortunately, know nothing about object files beyond my general
    figuring that they contain mostly compiled code with various hard
    addresses substituted by lookup symbols (perhaps?). Despite, I would
    like to create an assembler that can create LINK.exe compatible WIN32
    code.

    I have done a check of HLA and NASM to see if they might have some
    source that I could look to for guidance, but HLA appears to translate
    from HL assembly to the local standard and NASM has the blurb:

    "obj is not exclusively a 16-bit format, though: NASM has full support
    for the 32-bit extensions to the format. In particular, 32-bit obj
    format files are used by Borland's Win32 compilers, instead of using
    Microsoft's newer win32 object file format."

    which makes me fear that the "newer win32 object file format" is not
    supported.

    Does anyone know of any simple, nuts-and-bolts assemblers that can
    produce modern .obj files and is (ideally) not itself written in
    assembly?
