Camel Book | = C = | can't happen

can vt.

To abort a job on a time-sharing system. Used esp. when the person doing the deed is an operator, as in "canned from the console". Frequently used in an imperative sense, as in "Can that print job, the LPT just popped a sprocket!" Synonymous with gun. It is said that the ASCII character with mnemonic CAN (0011000) was used as a kill-job character on some early OSes, but this is more likely to be short for `cancel'. Alternatively, this term may derive from mainstream slang `canned' for being laid off or fired.
