Pcbasic

This is a pre-release of the development branch of PC-BASIC. This is a belated follow-up to the earlier 16.06.0rc0 pre-release. Unfortunately that release had a few major issues that required further reworking.

This pre-release fixes a number of issues with the previous pre-release:
- Fixes crashes on maths errors
- Implements more faithful handling and memory storage of strings
- Implements floating-point operations whose results are closer to GW-BASIC
- Fixes screen lockups happening in programs that do a lot of printing
- Implements Wengier's suggestion for dealing with file names ending in dots
... and many other improvements; I'll add some more to this list when I have time.

Not all reported issues with the previos pre-release have been fixed; I am still researching how to display the candidate list for character composition with IME; this is unlikely to be fixed for the full release.

I am actively working on an OSX version; unfortunately this requires me to re-install my build environment, which is complicated on Mac.

Have fun!
Rob

This is a pre-release of the development branch of PC-BASIC. The code base in this branch has been much refactored to improve maintainability and allow the implementation of various new features. Among the improvements in this pre-release are:
- An interface based on SDL2 to supersede the ageing PyGame
- Experimental support for IME input methods
- Ability to call BASIC code from Python through the `basic.Session` API
- Threaded video and audio, not interrupted by I/O blocking
- Improved handling of Unicode file names and directories
- Correct memory handling of string literals in code
- Border support in `curses` interface on Unix text terminals

You are cordially invited to give this version a spin; due to the large number of changes some regressions are expected and it would be good to iron them out before the formal release. Note that an OS X release is in the works but not yet available.

All future development of PC-BASIC will take place on this branch; the 15.08 branch will continue to be supported but will only see limited bug fixes and no new features.

Have fun!
Rob
