[molpro-user] saving dump record and using it as initial guess

[elkeshavarz5 at sci.ui.ac.ir]

Dear Daniel
Thanks for your comments.
Again the error is there. It is looking for dump record 2101.2, and it  
is there (as it has been listed at the end of previous calculation,  
but it is ccsd wave function.)
Regards
Elham
