The following is a list of error messages which can occur when using the KERNAL routines. If an error occurs during a KERNAL routine, the carry bit of the accumulator is set, and the number of the error message is returned in the accumulator.
| NOTE: Some KERNAL I/O routines do not use these codes for error messages. Instead, errors are identified using the KERNAL READST routine. |
