In the US, the system standard default date form is MM/DD/YYYY. This controls the external appearance of dates for fields declared as DATE data types.
The DATEFORM template controls the form of DATE fields on data entry screens, it controls the form of the date you receive in variables via the FETCH, MOVE, and SET commands when no format override is specified.
It also controls the form recognized in FIND command syntax for DATE fields.
You may supply an alternate DATEFORM template. Another place where date
template defaults are specified is in the optional DFORMAT clause of the MODE COUNTRY
command. If you have used both, whichever you use last is the one that applies.
