A code with this ability to reconstruct the original message in the presence of errors is known as an error-correcting code. This triple repetition code is a Hamming code with m = 2, since there are two parity bits, and 22 − 2 − 1 = 1 data bit. Such codes cannot correctly repair all errors, however.
Sometimes, if the codes are designed with this purpose in mind, they can be used directly as a branch index upon return to the initiating program to avoid additional tests. AmigaOS. In AmigaOS, MorphOS and AROS, four levels are defined: OK 0; WARN 5; ERROR 10; FAILURE 20; Shell and scripts
