FTP Software
Year 2000
Software Checklist

Overview	This is FTP Software’s Year 2000 Software Checklist for software development:

1. Search Code (all utilities)	Search for "DATE", "Date", and "date" Search for "yr", "yy", "YR", and "YY" Search for "YEAR", "Year", and "year" Search for "DAY", "Day", and "day"
NOTE: Development should add to this list any other date-related approaches that they know or find while searching the code.

2. Investigate	Check each and every date-related function to confirm that there is no impact on proper code functioning based on Year 2000 requirements.

3. Test Plan	Test software products to insure the products will perform correctly. Testing should include specific Year 2000 dates and times. Figure 1 contains a list of dates to be considered and incorporated into the Year 2000 test plan.

4. Testing	Year 2000 testing program will become part of all FTP Software test plans for new releases between now and the end of Year 2000.
