BBC BASIC for SDL 2.0 version 1.27a released
« on: December 30, 2021, 05:17:13 pm »
I've released version 1.27a of BBC BASIC for SDL 2.0 - the cross-platform programming language for Windows, Mac OS, Linux, Raspberry Pi OS, Android, iOS and in-browser.  The changes in this version are as follows:

  • BASIC Interpreter / Run Time Engine

    Treat hexdecimal pointers in *LOAD commands etc. as unsigned numbers.

    Disable ON ERROR when in AUTO line-entry mode (64-bit and ARM editions only).

  • IDEs and Utilities

    The compiler utility can now build a 'web application' bundle to deploy online using https://wasm.bbcbasic.co.uk/bbcsdl.html?app=<URL of web bundle>.

    Fixed a race-hazard in the debugger which could cause a rare crash during variable listing.

  • Libraries

    Updated gfxlib and gfxlib_docs.pdf to add PROC_gfxPlotColumnListScale, PROC_gfxPlotRowListScale and FN_gfxLoadTextureSwapRGB.

    Updated audiolib to add PROC_mixCancel (truncates a sound effect) and PROC_mixSoundLevel (plays a sound effect at a specified level).

  • Example Programs

    Added candle.bbc (in examples/graphics), an animation of a burning candle, adapted from a program by David Williams.

    Added compiler directives to a few examples so they run as web applications without modification.


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, Raspberry Pi, Android, iOS, 64-bit Linux and in-browser editions, currently).
