Bob,
Thanks for the hint on Dissect and accompanying Labs - mighty tool.

Hi Martin,
I think that Don was referring to Dissect, the visual debugger that
Henry Rich created for the jqt environment.
It is available on the Package Manager for the jqt environment.
You may want to look at the labs for Dissect I & II for more information.
Cheers, bob
