80 >LWASM supports generating a proprietary object file format which is
81 described in <A
82 HREF="c558.html"
83 >Chapter 5</A
84 >. LWLINK is then used to link these
85 object files into a final binary in any of LWLINK's supported binary
86 formats.</P
87 ><P
88 >Object files are very flexible in that they allow references that are not
89 known at assembly time to be resolved at link time. However, because the
90 addresses of such references are not known, there is no way for the assembler
91 has to use sixteen bit addressing modes for these references. The linker
92 will always use sixteen bits when resolving a reference which means any
93 instruction that requires an eight bit operand cannot use external references.</P
94 ><P
95 >Object files also support the concept of sections which are not valid
96 for other output types. This allows related code from each object file
97 linked to be collapsed together in the final binary.</P
