To save storage space, many early generation software programs represent the year component of a date as a two digit number. For example, the year 1997 is represented by the number 97. Such programs suffer from century ambiguity, since the number 01 could represent the year 1901, 2001 or any other century. In addition, date arithmetic or comparison can often yield incorrect results because the correct century cannot be determined without further contextual information. These problems loom large as the new century approaches.
Because all versions of DADiSP internally represent the year field of a date by a 4 digit number, DADiSP does not suffer from century ambiguity. In addition, DADiSP employs 10 digit Julian numbers from all date arithmetic and comparison operations, always yielding correct unambiguous results.
