This allowed us to negotiate on various items within certain limits. Pretty clever I thought.
We did something similar in the Navy when we wanted to broadcast coordinates over the radio but couldn't use an encrypted channel - We'd use a ten-letter word with no repeated letters, with each letter representing 1 through 0. Not really "secure" in any meaningful sense of the word, but it was good enough for training flights.

The Hasselblad camera company uses that scheme for the date codes on its cameras and film magazines, too. "VHPICTURES" (For "Victor Hasselblad Pictures") translates to 1234567890. Kodak did the same thing for its lenses and camera bodies for a while too, using CAMEROSITY as the code word.
