In the second example, the monitor supplied the leading zeros.
After the monitor received the address, it printed that address
followed by its contents.
It also did one more thing which was not quite so apparent . It
stored the memory location that was examined as the last
opened address. Although this seems rather unnecessary now ,
this
extra step will prove very convenient when other monitor
commands are used .
Memory Dump
Examining one location at a time is fine, but this could be come
quite tedious should, say, 100 consecutive locations need to be
displayed. The monitor's answer to this dilema is referred to as a
memory dump.
A memory dump is accomplished by typing a period( . ), followed
by an address. The monitor will display the contents of each of
the bytes which follow the opened address up to the final
address , as specified in the command line. The amount of data
displayed depends upon the differnece between these two
addresses.

Data is always displayed in groups of eight or less. This simplifies
the reading of the data. For example, the contents of memory
location E009 is easily read as ED. The monitor again stores the
location of the last displayed location, EOOF.
Sometimes it is difficult to know how many locations one wishes
