broken arrow
[IBM] n. The error code displayed on line 25 of a 3270 terminal (or a PC emulating a 3270) for various kinds of protocol violations and "unexpected" error conditions (including connection to a {down} computer). On a PC, simulated with `->/', with the two center characters overstruck. In true {luser} fashion, the original documentation of these codes (visible on every 3270 terminal, and necessary for debugging network problems) was confined to an IBM customer engineering manual.
Note: to appreciate this term fully, it helps to know that `broken arrow' is also military jargon for an accident involving nuclear weapons....
broket
/broh'k*t/ or /broh'ket`/ [by analogy with `bracket': a `broken bracket'] n. Either of the characters `<' and `>', when used as paired enclosing delimiters. This word originated as a contraction of the phrase `broken bracket', that is, a bracket that is bent in the middle. (At MIT, and apparently in the {Real World} as well, these are usually called {angle brackets}.)
