Prime factor extractor
------------

This is a small routine to extract the prime factors of a number. If the
number turns out to be prime, a message is printed to that effect, otherwise
the prime factors are displayed.

The program was originally written for the Series 3a, and for convenience, the old source has been converted directly to the new. So if the program looks cheap, that's why.

Installation
------------

Put the .opo routine in any convenient directory on the system screen, and the .odb file in c:\system\apps\factors\. Tap on the .opo icon to run the program.

Use
---

The program is very simple to use. At the prompt, type your number. The
result will be displayed, and the program will prompt you for another number.
To stop the program, use the escape sequence (Ctrl-Escape).

Known problems
--------------

There is a problem which is insoluble without huge amounts of programming which
would be beyond the scope of this program (and this programmer). The problem is
that the highest long integer that opl32 can handle with integrity is only about
1073741824. If the processor has to handle numbers larger than this during
the program, the results will be inaccurate.
