This series of read-only built-in segment attributes are used in conjunction with the DateConvert logic command. These attributes are set to new values whenever a DateConvert logic statement (with the Format command option) is used. They are cleared before the logic command is executed.
If the DateConvert logic command is executed with the output Format command option, only the built-in segment attribute corresponding to that Format command option is set to the new value.
These attributes are listed in the following table with their primitive and length properties and example values for a particular date.
The Glb.Base and Glb.Century built-in segment attributes are also used in this process.
For the calculation of Glb.DC_WeekNo, weeks start on Sundays, and end on Saturdays. The value of Glb.DC_WeekNo for January 1 of any year is 1.
