The apostrophe trailing on the octal word indicates that it is a computed target
address. It is not what you would actually see in the .obj or .bin files.

If you want to force all references to be absolute instead of relocatable you
can add an ' .ENABL AMA'  pseudo-op before the .ASECT pseudo-op. This will
force all relative mode instruction references to become absolute mode. Or
of course you could just do ' CLR @#X' for that instruction.
