Thanks for that explanation, it makes a lot more sense now.  I also
didn't know this:
   sizeof(dynamic_array_var) = sizeof(pointer)

I wouldn't be making that mistake soon.  I better get my "annotation"
support fully working in the new INF help viewer, so I can add my own
notes to the Language Reference docs. :)

I never doubted heaptrc.   :)
