With the DF session parameter, you determine the
length of a date when converted to alphanumeric representation without an edit
mask being specified. The DF parameter is evaluated at
compilation time.
The sequence of the day, month and year components and the delimiter
characters used are determined by the profile parameter
DTFORM.

When the value of a date field is converted to alphanumeric format (for
example, in a MOVE,
DISPLAY,
WRITE or
INPUT statement) and no
edit mask is specified for the conversion, the default date format as
determined by the profile parameter DTFORM is used as edit
mask. The same is true for the input validation of a date variable used in an
INPUT statement: If no
edit mask is specified, the input is validated according to the date format
determined by the DTFORM parameter.
Note:
By using DF=I or DF=L, you can gradually
change your applications to use 4-digit year representations and at the same
time continue to make use of the flexibility provided by the profile parameter
DTFORM.
