Linking

The Windows Module compiler MC.EXE is called on a .DEF file, generating a .DFA file with MASM directives encoding the NE header. MC.EXE then calls MASM to assemble the .DFA file into a .DFO file, which is an OMF file containing sections composing the NE header. The resulting .DFO file is then passes to the 8086 linker LINK.EXE.
