## Changes from version c

Input script has changed some.

- The scattering symmetry is now specified with the data variable ScatContSym.
This name implies that this is the scattering symmetry of the scattering
continuum orbital. The variable ScatSym is now used for the scattering
symmetry of the total N or N+1 electron state.
- New commands have been added to compute the energy expressions and dipole
matrix expression for scattering from open degenerate shells. See test17 and
test18 for examples.
- GenFormPhIon
- generate formulas for the potential and dipole matrix elements
- GetCro
- run the nonlinear cross section program

- The format of the energy expression in the data set EngForm has also changed
somewhat.
- Most input concerning orbital numbering has changed. The orbitals are grouped
by their degenerate shells. Thus orbitals are selected and energy expressions
are given interms of the shells.
