 In ADL mode, the program is aware of the full address space. The Agon MOS loads programs by default to address $40000, so if ADL mode is set (#define ADL), the init.asm include file will set the .org $40000 directive.
 
-In Z80 legacy mode, the program will, from its point of view, be located from address $0000.  The program will have 32kb of address space to $7FFF available to itself. Note, the SPS stack expands downwards from $7FFF, so if your assembled code is very large, you need to make sure it doesn't clas with the stack.
