Clarification using _MEM

[DSMan195276]

With arrays.   Point to an element in an array and the SIZE changes depending upon that element.  Seems odd to me, but that's just the way it's always been.  /shrug   See my demo above. 

I suppose I was picturing the `_OFFSET` and `SIZE` in the existing `_MEM` being changed (since the comment says "changes"). Your code example doesn't change the original `_MEM` instance, it's creating new ones for each `_Mem()` call that you will then have to then `_MemFree`.
