From the code article:
- In the days when Morse code was widely used, elaborate commercial codes that encoded complete phrases into single words (five-letter groups) were developed, so that telegraphers became conversant with such "words" as BYOXO ("Are you trying to crawl out of it?"), LIOUY ("Why do you not answer my question?"), and AYYLU ("Not clearly coded, repeat more clearly."). The purpose of these codes was to save on cable costs.
Should this be added to the Morse code article?
Probably, but I also put it back into code; it was a good example of the data compression use that wasn't otherwise well covered there; I also gave it a slightly better introduction. --LDC
