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 difference between, e.g., a record with and without its representation defined by stepping through and showing the changes to the object in memory. It would 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 multiple memory views that update automatically!

All the best
John
