[molpro-user] FCI saving and loading vectors

Dear Molpro users,

I would like to save FCI vectors for several excited states and
then use them again as a starting point for a subsequent FCI
diagonalization. In this mailing list, I have found a way to save and
load the ground state FCI vector, which works fine:

   fci;state,1;davidson,,,1.40,,,,,0
    fci;state,1;davidson,,1.40

As I need to extend this method for the excited states,
I tried this modification:

   fci;state,10;davidson,,,1.40,,,,,0
    fci;state,10;davidson,,1.40

but it only saves/loads the FCI ground state.
How to accomplish my idea?

Thanks,

PRK
