Commodore 128 System Manual page 412

Memory is displayed in the following format:
>03000 45 58 2E 56 41 4C 55 45:EX.VALUE
Memory content may be edited using the screen editor. Move the
cursor to the data to be modified, type the desired correction and
hit RETURN. If there is a bad RAM location or an attempt to
modify ROM has occurred, an error flag (?) is displayed. An
ASCII dump of the data is displayed in REVERSE (to contrast with
other data displayed on the screen) to the right of the hex data.
When a character is not printable, it is displayed as a reverse
period (.). As with the disassembly command, paging down is
accomplished by typing M and RETURN.
EXAMPLE:
