= O =
overflow bit n.
1. [techspeak] A flag on some
processors indicating an attempt to calculate a result too large
for a register to hold. 2. More generally, an indication of any
kind of capacity overload condition. "Well, the Ada
description was baroque all right, but I could hack it OK
until they got to the exception handling ... that set my
overflow bit." 3. The hypothetical bit that will be set if a
hacker doesn't get to make a trip to the Room of Porcelain
Fixtures: "I'd better process an internal interrupt before the
overflow bit gets set."
