-
-Go, start execution. 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. 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. Note that first instruction is executed without effect of
-breakpoints. It means that if there is a breakpoint at start address
-then it will not be hit.

-After execution is started the <tt>Simulaton started</tt> message
-appears with value of PC where the execution started and the simulator
-is ready to accept other commands while the simulation is running in
-background.
-
-<!--If execution stops the simulator first writes out a number which is
-the reason of the stop (this is a diagnostic feature, it will be
-improved in future versions). Reason can be:
-
-<dl><dt>0
-
-<dd>There is no reason to stop. This number should never appear.
-
-<dt>1
-
-<dd>Serious error for example unknown instruction code which is
-impossible to execute.
-
-<dt>2
-
-<dd>Invalid address used in an instruction. For example indirect
-address is bigger then 127 in 51 type of controller. Execution can be
-continued but result will be undefined.
-
-<dt>3
-
-<dd>Stack overflow. Execution can be continued but result will be
-undefined.
