\ The dump utility gives you a formatted hex dump with the ascii
\ text corresponding to the bytes on the right hand side of the
\ screen.  In addition you can use the SM word to set a range of
\ memory locations to desired values.  SM displays an address and
\ its contents.  You can go forwards or backwards depending upon
\ which character you type. Entering a hex number changes the
\ contents of the location.  DL can be used to dump a line of
\ text from a screen.
