  15.       </a> Hexadecimal dump of a memory region. First parameter specifies
  16.       memory. It can be name of an address space or a chip, and can be checked
  17.       using <a href="cmd_general.html#info_memory">info memory</a> command
  18.       which lists size and name of all available memories.
  19.       <p><b>start</b> and <b>end</b> parameters can be used to specify the
  20.         first and last address of the dumped region. If <b>end</b> is omitted
  21.         then 64 memory location is dumped. If both <b>start</b> and <b>end</b>
  22.         are omitted then next 64 memory location will be dumped out. Every time
  23.         when dump command is used the address of last dumped memory location is
  24.         stored and next dump command automatically continues at next address. </p>
  25.       <p>Last parameter can be used to specify how many memory locations should
  26.         be dumped out in one line. It is 8 by default. </p>

  156.     First two parameters specify the address where the list starts. First
  157.     parameter is address where the command starts to search an instruction. This
  158.     search goes forward. When the first instruction marked by code analyser
  159.     found the simulator skips as many instructions as you specify in second
  160.     parameter. If <b>offset</b> is negative the simulator goes backward and
  161.     skips specified number of instructions. Default value of <b>start</b>
  162.     parameter is last address which was listed by previous <b>dis</b> command
  163.     and default value of <b>offset</b> is -1. It means you can make continuous
  164.     list repeating parameterless <b>dis</b> command.
  165.     <p>In third parameter you can specify how many instructions you want to
  166.       list. Default value is 20. </p>
