Mister T's Mathematical Diversions

My Programs, mostly graphically illustrating mathematical ideas or problems, are written in BBC BASIC for Windows with embedded Assembly Language due to it's straightforward, efficient style. Listings included here will run if cut-and-pasted into BBC BASIC, and .exe files will run stand-alone. BBC BASIC for Windows is a user-friendly, painless way to utilise x86/Pentium Assembly Language.

Some programs also have
Visual C# versions. To run these you will need to install the .NET Framework.

My tutorial
Assembly Language programs are one of the more often visited pages

Some of the dynamical programs are developed from material clearly explained
by Dr. David Acheson of Oxford University in his book "From Calculus to Chaos"

An excellent reference for some of the advanced and/or obscure mathematics I've needed is to be found at

In addition to the Help section within BBC BASIC for Windows, the best reference for Assembly Language is:
The Art of Assembly Language by Randall Hyde (Published 2010)

Where to Obtain BBC
BASIC for Windows

Version 6.11a of BBC BASIC for Windows is the latest revision as of September 2017

It includes many features you'd expect in C++, such as structures and structured prototypes.

It's available from, and indeed written by:
Richard Russell
and costs just 30 ( or around $50 )

Many of my executable programs run in full screen with NO mouse control.
Don't panic!
Alt-F4 will always parachute you back to normality.
