Normally, I would agree but XDC is a very special case with very broad 
requirements. As a full z/OS system debugger, Dave Cole has many requirements 
that are atypical. E.g. does he want the ability to display environment 
variables from all processes instead of just the process being debugged? He 
also has restrictions such as debugging SRB, SVC, PC routines and more. More 
than likely, he doesn't want to use SRB's & IRB's to gather the data when 
access registers are simpler.
