I've updated the Console Mode editions of BBC BASIC to v0.40. These lightweight editions have no graphics or sound, but are ideal for computing tasks or scripting. This release fixes a couple of minor bugs and comes with a new example program, 'solve.bbc' which solves simultaneous equations using matrix inversion.

Thanks the Darren Storer on groups.io for pointing this out.
