Is there a RPN operation that does nothing? (NOP)

[Willy R. Kunz]

For the HP-67 only, there's a weird, undocumented way to program a NOP:

- Enter GTO.2
- Press keys A and D simultaneously

This inserts the key code 32 24, which does nothing (there's no g (i) command).

The nice thing is that the command executes in a mere 7 ms.

Just for fun, I've added this NOP command to my RPN-67 and 97 simulators. Simply enter g (i), or EXT 0 on the RPN-97.
