Yes, the problem is, that it's not allowed in ISO Modula-2.

As long as your favorite M2 compiler manufacturer doesn't implement
the ISO_M2 language changes, there is no help.

I don't know whether you got it, so here is my answer again:

location := SYSTEM.ADDADR(location, SIZE(location^))

Note, that SYSTEM.WORD is not ISO_M2, although an implementation is
allowed to extend ISO_M2's SYSTEM module.

                        ^ POINTER TO SYSTEM.LOC in ISO_M2.
