Edit: To clarify my question — to the best of my knowledge, while the VAX had a higher level of indirection of indirection in instructions than the x86, the 68K has exactly the same level of indirection.

Some architectures have instructions such as LDI imm that load MEM[MEM[imm]]--indirect memory references.

I have little knowledge of 68k, but I understand that memory indirect addressing will deference its operand twice [1].

Ah yes, you & grandparent are right, I had forgotten about the existence of these modes.
