v0.4

Fixed a few problems:

• Line insertion/removal/replacement had a really subtle but nasty bug.
• If RND() was called with no parameter, interpreter hung. Now defaults to 32767.
• Sometimes an Error 5 came up when a program finished.

Debugging continues but this version is much more usable.

v0.2

This is the first public release of my 6502 Tiny BASIC interpreter. Still lots of bugs, but it works well enough to be fun as a demo.
