Factor 1.1 (details)	49/50 ENG 8 KB / 2 KB
This library contains a high speed factoring program, with verbose messages. It is about twice as fast as the built-in routines, and much more than that for numbers of 16-38 digits.

HLDRAW 2.6 (details)	49/50 ENG 15 KB / 3 KB
HLDRAW does what WIREFRAME should have done: fast, true photographic, hidden line removed 3D plotting. It is possible to easily adjust the viewpoint so that you can rotate the graph.
By Jurjen N.E. Bos.	2001-05-21

HLDRAW 2.61 (details)	49/50 ENG 17 KB / 4 KB
Equivalent to WIREFRAME plot, but with hidden line removal and shading of "underside" of 3D graph. For the 49g+ and 50g (ROM 2.15) only. The previous version only worked on older ROM revisions (older 49G ROMs only?). Modified to work with most current ROM. Source code has been updated as well (for on-calc compiling only).

IA2B2 (details)	48 ENG 2 KB / 1 KB
Small User RPL program that extends the functionality of PA2B2 to any number of less than 25 digits. (It could be extended to any number, but it will be a lot slower.) Its result is a list, which will be empty if there is no way to write the number as a sum of two squares, which is often the case.
