+
+<a name="run"><h3>r,run,go [start [stop]]</h3></a>
+
+This command starts the execution of the simulated program.
+
+<p>Parameters are optional. First parameter specifies start address of
+the execution. By default execution starts at address specified by
+actual value of the PC. This can be overridden by first parameter.
+
+<p>If second parameter is specified it places a dynamic breakpoint at
+specified address which stops the execution. If stop address is not
+given the simulator stops if it reaches a breakpoint, or the CPU
+accepts an interrupt and <b>stopit</b> option is TRUE, or fatal error
+occures or <a href="#stop">stop</a> command is used on an other
+console, or ENTER key is pressed on the console where the run command
+was issued.
+
+<p>If program execution is started the console is <i>frozen</i> it is
+not possible to give commands on this console to the simulator while
+execution is running. If it is needed to control the simulator during
+program execution then more consoles can be used. See using <a
+href="mulcons.html">multiple consoles</a> for more information.
+
+<p>Note that first instruction is executed without effect of
+breakpoints and simulation will be started afterwards. It means that
+if there is a breakpoint at start address then it will not be hit. See
+following example:
