DATFORM

The DATFORM system initialization parameter specifies the external date display standard that you want to use for CICS date displays.

DATFORM={MMDDYY|DDMMYY|YYMMDD}
An appropriate indicator setting is made in the CSA. It is examined by CICS supplied system service programs that display a Gregorian date. CICS maintains the date in the form 0CYYDDD in the CSA (where C=0 for years 19xx, 1 for years 20xx, and so on; YY=year of century; and DDD=day of year), and converts it to the standard you specify for display.
The DATFORM option selects the order in which the date is to be displayed. It does not select the format of the year. Both YY and YYYY formats are displayed.
MMDDYY
The date is in the form of month-day-year, MMDDYY and MMDDYYYY.
DDMMYY
The date is in the form of day-month-year, DDMMYY and DDMMYYYY.
YYMMDD
The date is in the form of year-month-day, YYMMDD and YYYYMMDD.
