The vgVar.systemJulianDateFormat system variable is used as a possible value for the dateFormat property of DataItem parts. vgVar.systemJulianDateFormat contains an 8-character pattern that includes DDD (for numeric day) and yyyy (for numeric year), with characters other than D, y, or digits used as separators.
For COBOL programs, the system administrator for EGL runtime services sets the default format during installation.
