Using the Statement

If the type (item 5) is S (short), the result is returned in the destination field as three characters (for example, “Wed”). If the type is L (long), the result is returned in the destination field as up to nine characters (for example, “Wednesday”). If the source field is blank, the destination field is set to blank.

Restrictions

The destination must be an alpha field type and the source must be a date/time field type containing at least year, month, and day.

Execution Errors

If the source field is one of the Gregorian date/time field types, a non-recoverable error occurs if it does not contain the year, month, and day parts. If the source field is one of the Julian date/time field types, a non-recoverable error occurs if it does not contain the year and day parts.
