I wrote a short program that dumps memory in hex format.
It takes a hex address argument off the command line
and displays the contents of that memory address on 
the screen in hex format like so:

C:\gnuwin32\src\src\peek f000

et cetera ....

anyways, I get an exception in the gnu-win32 handler when I try to display
system memory areas, like low memory 00000417 for example (numlock status
byte).

What do I have to do to be allowed to examine any area of storage?
