fewer
bytes
than
the
range, DEBUG uses
the
list
until all locations
in
the range
are
filled.
•
If
the
list
contains
more
bytes
than
the
range,
DEBUG
ignores the extra values
in
the list.
•
If
you enter only
an
offset
for

starting
address of the
range, DEBUG uses the segment indicated by Register
DS.
