Year 2000 Considerations

CA Disk is Year 2000 compliant. Year 2000 date testing was accomplished on a P/390 with CA Disk 9.0 (PD9839) installed. All functions were tested while the system was IPL'd with the following dates:

• 1999.365 — end of century
• 2000.001 — beginning of century
• 2000.060 — February 29

CA Disk follows all IBM conventions to identify dates within specific centuries in the following areas:

• Non-VSAM data sets use discontinuous binary, an xxyyy format where xx is from 0 255 and is the year when added to a base of 1900.
• VSAM and tapes use a separate century field.
• The FILES uses the discontinuous binary for all dates.
• CA Disk REPORTS use the mm/dd/yyyy.
