BBC BASIC for SDL 2.0 version 1.21a released

Copied from Richard's post at

I've released version 1.21a of BBC BASIC for SDL 2.0 - the cross-platform programming language for Windows, MacOS, Linux, Raspbian, Android, iOS and in-browser. The changes in this version are as follows:

BASIC Interpreter / Run Time Engine
Mapped keyboard shortcuts Cmd+A, Cmd+C, Cmd+F, Cmd+V, Cmd+X and Cmd+Z to their Ctrl equivalents for improved compatibility with Apple Macs.
Fixed a couple of minor differences between the 32-bit x86 editions and the ARM/64-bit editions.

IDEs and Utilities
Added compiler directives to to simplify building a standalone version in BB4W.
Modified,, and to be compatible with BB4W as well as BBCSDL.
Added to support Box2D Debug Graphics, largely compatible with the equivalent BB4W library.
Fixed a bug in affecting Gear Joints on 64-bit platforms.
Fixed a bug in causing the trackbar control not to scale to the specified range.
Fixed a bug in causing mouse clicks not to be reliably detected.

Example Programs
Added (in examples/physics) which demonstrates combining Box2D and 3D rendering.
Added (in examples/graphics/) which is another shader demo.
Modified to increase the range of level adjustment (100% is now 'mid-range').
Modified the other demos in examples/physics to take advantage of the box2ddbg library (press D to display the Debug Graphics).

This version may be downloaded, for all the supported platforms, from the usual location. The GitHub repository has been updated (used to build the MacOS, Raspbian, Android, iOS, 64-bit Linux and in-browser editions, currently).
