Hi Tony,

First let me point out that very little work has been done on the debugger for a few years. It really needs an overhaul to fix some issues and add new functionality, but unfortunately we haven't been able to find anyone willing to work on it.

To answer your specific questions:

1. Unfortunately this is not supported. The "Arrays" view was the beginnings of an attempt to provide an array/viewer viewer, but unfortunately it was never completed.

2. The second variables view is used to add variables that you want to be displayed when you mouse over one the process icons in the Parallel Debug view. This simplifies seeing the values of the same variable across different processes, rather than having to select the stack frame in the Debug view.

Incidentally, there is another view which I forgot to enable by default in the current release called the "Debug Locations View". You open this by going to Window>Show Views>Other... then selecting Debug Locations View from the Parallel Tools folder. This gives you summary of were all the suspended process in the job are currently located, and how many are at each location.

3.  It looks like the debugger got confused about the variable "h" for some reason. There's a message about 'Unknown variable "h[0..10]"'. Better handing of these types of problems is one of those things that needs to be worked on. For now, I would suggest stopping and restarting the session.

Hope this helps,

Greg

Ideally we would use a syntax like x[11:17] or A[1,*] etc. In gdb I would use x/7fg x+11 which is not so nice but it works and you don't have to print element by element. I can't figure how to do this in eclipse.

I am sorry its not a proper log file but a screen capture. I had not realized the log file is lost when eclipse is restarted - I can't reproduce the problem right now, but it was not a one off.
