Find yourself writing programs in BBC BASIC? Do your programs ever involve floating point maths? Well we’ve got some good news for you!
The Archimedes BASIC Compiler (ABC) 5.00 has been extended with a new option to directly output Vector Floating Point maths instructions which then run on the hardware floating point unit built into many recent Arm processors. This gives a considerable speed increase compared with its predecessor the Floating Point Accelerator which is often emulated now.

Portable Network Graphics, with file extension PNG and often pronounced Ping, is a common bitmap graphics format which offers lossless compression for faster transfer over the internet. PNG sits somewhere between Sprite, which is uncompressed, and JPEG used for photos, which uses lossy compression (throwing some information away) to shrink the file even smaller.
There are two aspects to the new PNG support:
Underneath this there’s a new support module, called CompressPNG, which does the real work and which other applications will be able to make use of.
If you are a developer and you’d like to add PNG export to one of your own applications it’s simply a case of making a few system calls from whatever language you prefer to use. It’s very similar to the CompressJPEG module which has shipped since RISC OS 3.60, so much so that Paint has also gained the ability to save out as JPEG via that same approach.
