PL/I PL/1 Year 2000 built-in functions

The Year 2000 built-in functions implemented in IBM's workstation PL/I compilers -- OS/2, AIX, Windows NT (some also in Windows 95) -- are outlined in the following list. Note that these functions (where appropriate) can also handle 2-digit years with 100-year windowing, if required, as part of IBM's Millennium Language Extensions for those same compilers.

These date functions will work on dates on or after 15th October 1582 (that is, a little after the date when Christopher Columbus is credited with discovering America).
