Hi Fritz,

I just wondered if you'd ever found a solution to this that doesn't involve=
 going external to Eclipse's debugging facilities. I'm intending to present=
 a very brief summary of Ada's facilities for defining representations to a=
 bunch of uninterested C++ programmers and would like to show them the diff=
erence between, e.g., a record with and without its representation defined =
by stepping through and showing the changes to the object in memory. It wou=
ld be nice to do this in Eclipse as I'm familiar with that, and it's pretty=
, but I suppose I could do it in GPS if I could find a way of having multip=
le memory views that update automatically!

All the best
John
