      A system is proposed for creating table archives of hardly definable functions in the form of FORTRAN subroutines, where digital data is stored in the DATA statement list. To reduce the digital data, approximation spline coefficient should be stored. An efficient algorithm "for natural spline construction is described.
      An example illustrating a program, used to calculate photo ions scattering cross-sections on free electrons, is shown.
