Highlights are

- real, complex and interval scalars and matrices,
- a programming language, with local variables, default values for parameters, variable parameter number, passing of functions,
- two and three dimensional graphs,
- marker plots,
- density and contour plots,
- numerical integration and differentiation,
- statistical functions and tests,
- differential equations,
- interval methods with guaranteed inclusions,
- function minimizers (Brent, Nelder-Mean),
- Simplex algorithm,
- interpolation and approximation,
- finding roots of polynomials,
- calling of functions in external DLLs,
- sound playing,
- Fast Fourier transform (FFT),
- an exact scalar product using a long accumulator,
- Postscript graphics export (thanks to Eric Boucharé)

and lots more. The specials of the notebook versions (Windows, OS/2) are

- editable command window with comments,
- normal OS GUI,
- graphics export in various formats (WMF over the clipboard)
