[A89] Re: org directive in a68k


I understand the linker places a relocation table at the end but I am not
linking this with the 89's linker.  I am programming some flash chips on a
circuit board for school.  I can guarantee this code will always run from
location $20000.  I could write a linker that changes the base address of my
code but this would be more work than i think necessary.  Seeing how there
has been a method for setting the base address(in the source) in every
assembler i have ever used, i'm sure there is one here in a68k.  The
question is how.
