SciWriter is an XML-based scientific editor that completely integrates writing mathematics and text in the same environment. The native document format is a subset of XHTML 1.1 and MathML 2.0 Presentation Markup.
Print Publishing: A SciWriter document can be exported to LaTeX and be published as PDF, Postscript or DVI.
Web Publishing: SciWriter documents can be published on the web as XHTML+MathML or as HTML with equations as images.

Factorizer may be used:
(1) to get the prime decomposition of all numbers in a range of numbers
(2) to get all factors of a single number or all factors of all numbers in a range
(3) to find only the prime numbers in a range of numbers
(4) to find pairs of prime numbers (e.g. 107 and 109) in a certain range
(5) to count (without displaying) the prime numbers in a range of numbers
(6) to find Fermat and Mersenne primes < 2,147,483,647

Robot4 (tm) is a Robotic Arm Movement program where the arm is moved from a given position to a desired
position. The program finds the angles necessary for the desired position. (I think this is the idea!) Problem came from NASA.

Robot4 is an Inverse Problem example. It wants to solve how to move from starting point 'A' to target point 'B'.
Solutions to Inverse Problems are easy with Fortran Calculus language. See 'Rob4User.fc' file.
