ill-behaved
(1)[numerical analysis] Said of an algorithm or
computational method that tends to blow up because of
accumulated roundoff error or poor convergence properties.
ill-behaved
(2)Software that bypasses the defined operating system
interfaces to do things (like screen, keyboard, and disk I/O)
itself, often in a way that depends on the hardware of the
machine it is running on or which is nonportable or
incompatible with other pieces of software.
In the IBM PC/mess-dos world, there is a folk theorem (nearly true) to the effect that (owing to gross inadequacies and performance penalties in the OS interface) all interesting applications are ill-behaved.
See also bare metal. Opposite: well-behaved, compare PC-ism.

well-behaved
Programs that do not deviate from a standard. A program that is not well-behaved (ill-behaved) typically bypasses the operating system or some other control program and accesses the hardware directly in order to improve performance.Copyright © 1981-2019 by The Computer Language Company Inc.
