+In some applications, it is not feasible for the debugger to interrupt
the program's execution long enough for the developer to learn anything
helpful about its behavior. If the program's correctness depends on its
real-time behavior, delays introduced by a debugger might cause the
In this example, @code{add} is the name of the bytecode, and
@code{(0x02)} is the one-byte value used to encode the bytecode, in

the stack before and after the bytecode executes. Beforehand, the stack
must contain at least two values, @var{a} and @var{b}; since the top of
the stack is to the right, @var{b} is on the top of the stack, and
