Hi Eli,

Nope.  You're right, Eli.  It doesn't help.  I tried it.  I also tried sourcing
a file that had a series of "x/3x 0xNNN00000" commands at 1 Meg steps.
That didn't work either because GDB quit as soon as an invalid address
was attempted.  So, for me, the ideal solution is a command that yields
(figures out) the valid address ranges, and an adequate backup would
be to tell the "source" command to keep going after a failed command.
Perhaps this is a "request for enhancement", though I hoped there might
already be some hackish way of accomplishing what I need.

Thanks!  Cheers - Bruce
