No, that definitely wasn't it: this is of the "numeric code plus text
string" type, although it's interesting because it has multiple-length text
strings to trade off verbosity/helpfulness. It kind of reminds me of what

only a brief description, but if you type DESCRIBE you get the full monty.
That must have saved a lot of LA34/36 paper. :-)
