      - Common functions such as exp, ln, sqrt, sqr etc.
      - Trigonometric, Hyperbolic  functions
      - Numerical Integration, e
      - Equations can be solved
      - Special functions (Gamma, Bessels, Si, Ci, erf)
      - Statistic functions (Average, Standard deviation, Sum, Random,
        Gauss random, statistical variance )
      - FOR-type loop
      - Tape of results
      - Assistant and debug: error position fixed
      - Plot f(X), Contour Plot f(X,Y), Color Shading  f(X,Y),
        3D-Plot f(X,Y)
      - Print results, graphics and print preview
