Using Intrinsic Functions or the ACCEPT Statement to Retrieve Current
Century
You can also use one of the following intrinsic functions to retrieve the
current century or a 4-digit year:
- CURRENT-DATE
- Returns the current 4-digit year, as well as other information about
the current date and time.
- DATE-OF-INTEGER
- Takes an integer date, the number of days since December 31, 1600, and
returns a Gregorian date with a 4-digit year in the form YYYYMMDD.
- DAY-OF-INTEGER
- Takes an integer date, the number of days since December 31, 1600, and
returns a Julian date with a 4-digit year in the form YYYYDDD.
- DATE-TO-YYYYMMDD
- Converts a 2-digit year Gregorian date to a 4-digit year Gregorian date.
- DAY-TO-YYYYDDD
- Converts a 2-digit year Julian date to a 4-digit year Julian date.
- EXTRACT-DATE-TIME
- Extracts a part of the date or time information contained in a date,
time or timestamp item. The year is extracted as a 4-digit year or a 1-digit
century.
- YEAR-TO-YYYY
- Converts a 2-digit year to a 4-digit year.
The FROM DATE YYYYMMDD phrase of the ACCEPT statement can be used to retrieve
a 4-digit year Gregorian date from the system. The FROM DAY YYYYDDD phrase
of the ACCEPT statement can be used to retrieve a 4-digit year Julian date
from the system.
