This system call has been implemented in OZ v4.5.
The call is useful to get country localized full or short string of day of the week or month name. An example of the usage can be read in Calendar popdown source code.
The localized string of 'Today, Yesterday or Tomorrow' is available. It is used by GN_Sdo to output today instead of formatted date as seen in Index application.
The buffer on entry has to be in segment 2 or 3, segment 1 is used by the Date Filter Definition Table (FDT).
GN_Dei, convert zoned format date to internal format
GN_Die, convert internal format date to zoned format
GN_Gdt, convert an ASCII string to an internal binary date
GN_Pdn, write number as decimal ASCII string
GN_Gmd, Get (read) machine date in internal format
GN_Pmd, put (set) machine date
