11 <a name="dump"><h3>dump <i>memory_type [start [end [bytes_per_line]]]</i>
12 <br>dump <i>bit_name...</i></h3></a>
14 First form can be used get content of memory while second form can be
15 used to check value of bit or bits.
20 <a name="dump_memory"><h4>dump <i>memory_type [start [end
21 [bytes_per_line]]]</i></h4></a>
23 Hexadecimal dump of a memory region. First parameter specifies
24 memory. It can be name of an address space or a chip, and can be
25 checked using <a href="cmd_general.html#info_memory">info memory</a>
26 command which lists size and name of all available memories.
28 <p><b>start</b> and <b>end</b> parameters can be used to specify the
29 first and last address of the dumped region. If <b>end</b> is omitted
30 then 64 memory location is dumped. If both <b>start</b> and <b>end</b>
31 are omitted then next 64 memory location will be dumped out. Every
32 time when dump command is used the address of last dumped memory
33 location is stored and next dump command automatically continues at
36 <p>Last parameter can be used to specify how many memory locations
37 should be dumped out in one line. It is 8 by default.

150 ASCII charactes of bytes dumped out in the line. If value of the
151 memory cell is not printable than a dot is dumped out.

201 Disassemble code. This command can be used to list disassembled
202 instructions which discovered by the <a href="analyzer.html">code
203 analyzer</a>. First two parameters specify the address where the list
204 starts. First parameter is address where the command starts to search
205 an instruction. This search goes forward. When the first instruction
206 marked by code analyzer found the simulator skips as many instructions
207 as you specify in second parameter. If <b>offset</b> is negative the
208 simulator goes backward and skips specified number of
209 instructions. Default value of
210 <b>start</b> parameter is last address which was listed by previous
211 <b>dis</b> command and default value of <b>offset</b> is -1. It means
212 you can make continuous list repeating parameterless <b>dis</b>
215 <p>In third parameter you can specify how many instructions you want
216 to list. Default value is 20.

262 listed address. Next element on the list can be an asterix (<b>*</b>)

264 analyzer. <b>dis</b> lists marked instructions only so asterix never
265 appears in the list. Next element of the list is address displayed as
266 six digit hexadecimal number. Address is followed by hexadecimal dump
267 of instruction's code. Last element of the list is disassembled
268 instruction. Every number appeared on the list is hexadecimal number.
