Nature of problem:
This program is a revision of Klotz's program for calculation of the matrix elements of the one-body spin-orbit interaction using multiconfigurational wave-functions. A recent correction has been included in the present version.

Reasons for new version:
The input and output formats have been changed to a more familiar, readable and convenient spectroscopic notation. In addition, a punch option has been added to punch the results which could be directly used for energy levels calculation for various j-manifolds.

Unusual features:
This is a double-precision program suitable for computers with short word lengths such as the IBM S360, AMdahl 470 V/6.

Running time:
Time of 1.1 seconds is required for the test run on Amdahl 470 V/6.
