BBC BASIC for SDL 2.0 version 1.06a released

Post by DDRM »

Copied from Richard's post on the Stardot forum: ... 2&p=246899

I have released version 1.06a of BBC BASIC for SDL 2.0, the cross-platform programming language for Windows, MacOS, Linux, Raspbian, Android and iOS. The changes in this version are as follows:

BASIC Interpreter / Run Time Engine

Added support for antialiased 2D graphics (extending SDL2_gfx).

Increased the maximum number of float parameters that can be passed by SYS from 6 to 8.

Fixed a bug in the PRINT statement whereby a comma didn't unset 'hex' mode (64-bit and ARM editions).

Modified the ARM and x86-64 assemblers so that the 'Jump out of range' error is not reported on the first pass if the destination label has been made LOCAL.

Modified the ARM assembler so that numeric values may be used as aliases for register names (this improves compatibility with Acorn's assembler).


Added '' to support antialiased 2D graphics. This is functionally very similar to the GDIPLIB library supplied with BBC BASIC for Windows.

Example Programs

Added '' (in the examples/graphics folder) to demonstrate antialiased graphics.

Added '' (in the examples/graphics folder), a Celtic Knot program by David Marples which also makes good use of antialiased graphics.

Added '' (in the examples/general folder; desktop editions only) which is a terminal program for Bulletin Board Services accessed by 'telnet'.

This new 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, iOS and 64-bit Linux editions, currently).
