By "8-digit date", I am assuming you mean "2-digit year, with slashes", such 
as (8,mdy/).

If date math exceeds the range of the 2-digit year, you should get "/OV".

My system has PFCMARK=20, and using the following:

=====
::end:
@entsel::xx(8,mdy/) = "12/01/19":
::yy(10,mdyy/) = xx:
::zz(8,mdy/) = xx + "40":
::show "'" & xx & "'" & yy & "'" & zz & "'":
::end:
=====

shows:

     '12/01/19'12/01/2019'/OV     '
