The 'YYYY' Dates Date Structure specifies the structure to be used for COBOL data items that were associated with an eight-digit
date transform when the catalog was designed, and the 'YYYY' Base Year constant specifies the base year used to interpret
date values containing a four-digit year.
The eight-digit date transform is specified during catalog design when the structure of end-user COBOL dates, with four-digit
years, varies for different end-user sites. Each end-user site can set this variable to the structure used in its files. The
default structure is YYYYMMDD (a four-digit year, followed by a two-digit month of the year, followed by a two-digit day of
the month).
The default base year is 0. The base year is added to a four-digit year value obtained from a COBOL data item when computing
a column date value and is subtracted from the column date year value when computing a COBOL data item that contains a four-digit
year.
- On the
Tools menu, click
Date Constants.
The
Date Constants tab is displayed.
- In the
YYYY Dates section, in the
Date Structure field, select one of the available structures:
- YYYYMMDD
- MMDDYYYY
- DDMMYYYY
- In the
'YYYY' Base Year field, enter a value (up to four digits) for the base year.
- Click
Save to save the changes to the catalog.
Tip: If you click
Defaults, the structure reverts to YYYYMMDD, and the base year reverts to zero.
