Hexadecimal and ASCII format, 16 bytes to a line, 7 lines a to a 
screen.  The up-down cursor keys un-shifted will move back or forward 
one line, shifted will move a screen at a time.  <> with the up or 
down cursor key will take you to the top or bottom of the file.  If you

back to byte 0 of the file.   The [DEL] key escapes from the current 
dump.
