COFF file format needed

[Andy]

Can anyone give me a pointer to a description of COFF (Common Object File 
Format). I need the most detailed spec available as I am writing an
extension to a LISP system to enable loading of compiled C code 'on the fly'
without exiting the LISP interpreter or relinking.

Also anyone who has done something like this or wants to discuss it is
welcome to email or call.
