+></H1
+><P
+>LWASM supports generating a proprietary object file format which is
+described in <A
+HREF="c886.html"
+>Chapter 6</A
+>. LWLINK is then used to link these
+object files into a final binary in any of LWLINK's supported binary
+formats.</P
+><P
+>Object files also support the concept of sections which are not valid
+for other output types. This allows related code from each object file
+linked to be collapsed together in the final binary.</P
+><P
+>Object files are very flexible in that they allow references that are not
+known at assembly time to be resolved at link time.  However, because the
+addresses of such references are not known at assembly time, there is no way
+for the assembler to deduce that an eight bit addressing mode is possible. 
+That means the assember will default to using sixteen bit addressing
+whenever an external or cross-section reference is used.</P
+><P
+>As of LWASM 2.4, it is possible to force direct page addressing for an
+external reference.  Care must be taken to ensure the resulting addresses
+are really in the direct page since the linker does not know what the direct
+page is supposed to be and does not emit errors for byte overflows.</P
+><P
+>It is also possible to use external references in an eight bit immediate
+mode instruction.  In this case, only the low order eight bits will be used. 
+Again, no byte overflows will be flagged.</P
