The notes did mention it in the last example.  this is what I did to reserve
memory and use it.  Somewhere in your code you put the line

buffer db 10 dup (?) ;this creates 10 bytes of memory space in your memory
(uninitialized)

so you can use a register (eg bx) to be the pointer that points to the
buffer by issuing the command:
mov    bx, offset buffer
bx will then contain the starting address of buffer.  From here on, you just
have to increment the value in bx to point to the next byte in the buffer.

Hope that helped.
