I recently downloaded MARK_INT.EXE 08/11/2012 and reran models previously constructed using the Robust Design Multi-state with State Uncertainty.  The models run on the earlier MARK vers ran fine with no error message.  When I reran the same models with the new vers I received the following error message when appending the new runs to the results - "**WARNING** Error number 0 from VA09AD optimization routine."
Phi dot postings discuss Error numbers 2 and 3, but no number 0.  May I assume 0 means no error, and this is just something now reported with the new parallel processing with multiple threads?
Thank you.
