  •  View Definition: meta bit 

    meta bit


    n. The top bit of an 8-bit character, which is on in character values 128--255. Also called high bit, alt bit, or hobbit. Some terminals and consoles (see {space-cadet keyboard}) have a META shift key. Others (including, *mirabile dictu*, keyboards on IBM PC-class machines) have an ALT key. See also bucky bits.

    Historical note although in modern usage shaped by a universe of 8-bit bytes the meta bit is invariably hex 80 (octal 0200), things were different on earlier machines with 36-bit words and 9-bit bytes. The MIT and Stanford keyboards (see {space-cadet keyboard}) generated hex 100 (octal 400) from their meta keys.
