$XABDAT_STORE

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