Disassemble code. This command can be used to list disassembled
-instructions which discovered by the code analyzer. First two
-parameters specify the address where the list starts. First parameter
-is address where the command starts to search an instruction. This
-search goes forward. When the first instruction marked by code
-analyzer found the simulator skips as many instructions as you specify
-in second parameter. If <b>offset</b> is negative the simulator goes
-backward and skips specified number of instructions. Default value of
+instructions which discovered by the <a href="analyzer.html">code
+analyzer</a>. First two parameters specify the address where the list
+starts. First parameter is address where the command starts to search
+an instruction. This search goes forward. When the first instruction
+marked by code analyzer found the simulator skips as many instructions
+as you specify in second parameter. If <b>offset</b> is negative the
+simulator goes backward and skips specified number of
+instructions. Default value of
<b>start</b> parameter is last address which was listed by previous
<b>dis</b> command and default value of <b>offset</b> is -1. It means
you can make continuous list repeating parameterless <b>dis</b>
under certain conditions; type `show c' for details.
