The assembly language for the CYBER 200, developed at CDC ca 1977. [CDC Pub 60256020]. [Jargon File] /me't*/ or /may't*/ or (Commonwealth) /mee't*/ A prefix meaning one level of description higher. If X is some concept then meta-X is data about, or processes operating on, X. For example, a metasyntax is syntax for specifying syntax, metalanguage is a language used to discuss language, meta-data is data about data, and meta-reasoning is reasoning about reasoning. This is difficult to explain briefly, but much hacker humour turns on deliberate confusion between meta-levels. [Jargon File]
