[Coco] Dump/edit memory in OS-9 or NitrOS-9?

[William Carlin]

Christopher,

The block number in the extended MDir does refer to the specific 8K memory
block number.  You can get a "map" of all blocks by using the standard
NitrOS-9 command "MMap".  The "PMap" command will show all tasks with a
Process ID and what 8K blocks are in use by that program.  In PMap the
blocks on the right are the program code and the blocks on the left are
data areas.  You can use the MEd command to view the program code blocks by
specifying the module name as the command line parameter.  I don't have
access to VCC right now but I think if you run MEd without a module name,
you can manually specify what 8K block of memory you want to examine/change.
