Abstract

Described is a software routine which compresses data recorded in an errorlog. The errorlog includes the following entries: (a) error codes identifying the type of error, and (b) time stamps showing the month, day and time of a particular error. Instead of recording separate entries for each error, the routine compares a present error with a previous one and only a single entry is made for errors having common characteristics. In particular, compression is achieved in two areas. If the current error occurs during the same date as the previous error in the log, the month and day information is omitted for the current error. Likewise, if the current error has occurred during the same half-hour time interval as the previous error, the time of day information is also omitted.
