$XABRDT_STORE

   The $XABRDT_STORE macro moves user-specified values into fields
   of the specified XABRDT. The expanded $XABRDT_STORE code executes
   at run time on a previously initialized (allocated) XABRDT, in
   contrast to the $XABRDT macro, which initializes the XABRDT at
   assembly time. The $XABRDT_STORE macro must reside in a code
   program section.
