<updated>2011-04-16T23:00:00Z</updated>
<content type="html">
&lt;p&gt;
Total internal revamp: Now a compiler rather than interpreter. Source errors are reported
by BASIC line number as well as source line/column.
&lt;p&gt;
Display defaults to 40 columns, emulates 80-column firmware more accurately. Character output
(&lt;code&gt;CHR$()&lt;/code&gt;, &lt;code&gt;INVERSE&lt;/code&gt;, etc) tweaked to match Apple
behavior.
&lt;p&gt;
Files written via DOS now persist in your browser via &lt;a href="http://dev.w3.org/html5/webstorage/"&gt;Web Storage&lt;/a&gt;.
&lt;p&gt;
Floating point and integer overflows are caught rather than propagating infinities and NaNs.
&lt;p&gt;
&lt;code&gt;DATA&lt;/code&gt; statements and &lt;code&gt;INPUT&lt;/code&gt; entries parse
more accurately as comma delimited, optionally-quoted strings. &lt;code&gt;RE-ENTER?&lt;/code&gt;
is shown on invalid &lt;code&gt;INPUT&lt;/code&gt; (and can be trapped via &lt;code&gt;ONERR&lt;/code&gt;)
&lt;p&gt;
Added &lt;code&gt;HGR2&lt;/code&gt; and page-flipping &lt;code&gt;POKE&lt;/code&gt; shims, plus a few &lt;code&gt;CALL&lt;/code&gt; shims
for graphics. Hires graphics are now to a 280x192 bitmap, rather than trying to be sneaky with a 140x192 bitmap.
&lt;p&gt;
Error codes can be distinguished in &lt;code&gt;ONERR&lt;/code&gt; via &lt;code&gt;PEEK(222)&lt;/code&gt;.
Out-of-memory and stack-overflow conditions reported where possible (this is
&lt;a href="http://cautionsingularityahead.blogspot.com/2011/03/stack-overflow-and-out-of-memory-in.html"&gt;
non-standard across browsers&lt;/a&gt;).
&lt;p&gt;
Tweaked samples that were dependent on language/environment quirks.
&lt;p&gt;
Updated code editor to (the much improved) &lt;a href="http://codemirror.net/"&gt;CodeMirror 2.0&lt;/a&gt;. On parse errors,
the cursor is moved to the offending line/character.

<updated>2011-01-29T23:30:00Z</updated>
<content type="html">
&lt;p&gt;
Fixed error handling issues, e.g. DOS errors w/ &lt;code&gt;ONERR&lt;/code&gt; and syntax
errors e.g. &lt;code&gt;10 INPUT PRINT&lt;/code&gt;
&lt;/p&gt;
&lt;p&gt;
Added &lt;code&gt;HSCRN(x,y)&lt;/code&gt; extension function.
&lt;/p&gt;
&lt;p&gt;
Fix mouse-as-joystick to hit full range of 0...255.
&lt;/p&gt;

<updated>2011-01-26T23:00:00Z</updated>
<content type="html">
&lt;p&gt;
No longer show paddles/joysticks automatically; rely on mouse-as-joystick primarily.
&lt;/p&gt;
&lt;p&gt;
Use &lt;a href="http://flashcanvas.net/"&gt;FlashCanvas&lt;/a&gt; for older IE versions, instead of
&lt;a href="http://excanvas.sourceforge.net/"&gt;excanvas&lt;/a&gt;, and switch to plotting hires
pixels/lines directly rather than relying on canvas scaling and line drawing.
&lt;/p&gt;
&lt;p&gt;
Added Gaussian Distribution 2D plot sample, by John Russ

<content type="html">
&lt;p&gt;
Added compatibility shims for &lt;code&gt;PEEK(78)&lt;/code&gt; and &lt;code&gt;PEEK(79)&lt;/code&gt;
for seeding the random number generator. On a real Apple these are incremented during the input
polling loop and are a good source of entropy for seeding a random number generator. In this
interpreter, they are simply generated by the JavaScript &lt;code&gt;Math.random()&lt;/code&gt; function.
&lt;/p&gt;

&lt;p&gt;
Added lexical highlighting in code editor via &lt;a href="http://codemirror.net"&gt;CodeMirror&lt;/a&gt;. Note that this only highlights tokens, it does not check statement or expression syntax. It will highlight invalid tokens and unsupported statements.
&lt;p&gt;
Mousing over the screen now updates paddle position - try the lo-res painting demo for an example.
&lt;/p&gt;
&lt;p&gt;
Lots of internal code cleanup with hopefully no behavior changes.

&lt;p&gt;
Added "Echo to Printer" option to allow copy/paste of output
&lt;/p&gt;
&lt;p&gt;
Big refactor of internals. Statement parsing and execution now separated. A library of statement functions are
used for execution. Hopefully nothing broke - all unit tests still pass.

&lt;p&gt;
When run under &lt;code&gt;cscript.exe&lt;/code&gt;, the program still blocks until the user
presses Enter when a &lt;code&gt;GET&lt;/code&gt; statement executes, but the entered
characters are returned by subsequent &lt;code&gt;GET&lt;/code&gt; statements.
&lt;/p&gt;

<content type="html">
&lt;p&gt;
Tracked down source of IE perf issues when drawing with paddles; when the thumb/stick moves,
IE does a relayout/repaint of any content above the paddle in the HTML flow. If I delete the
page header it's silky-smooth. Unfortunately, any text above the screen seems to make it fall
off the deep end - so no fix yet without gutting the page.
&lt;/p&gt;
&lt;p&gt;
Undid "Line breaks from &lt;code&gt;PRINT&lt;/code&gt; now clear to the right edge" - doesn't repro on Apple. &lt;em&gt;What was I thinking?&lt;/em&gt;
&lt;/p&gt;

<updated>2009-05-06T12:00:00-08:00</updated>
<content type="html">
&lt;p&gt;
A bunch of performance tweaks based on IE8's JavaScript profiler. While they look good on paper,
they mean diddly-squat to perceived performance. Don't precalc default variable values, avoid DOM
changes that are no-ops, and (sigh) don't scan the whole screen looking for &lt;code&gt;FLASH&lt;/code&gt;-styled
cells - maintain a list instead so perf isn't impacted if there are none.
&lt;/p&gt;

<content type="html">
&lt;p&gt;
Expressions are now just-in-time compiled to JavaScript. Screen updates are the real bottleneck, though,
so this isn't a big performance boost. Performance comparison (on my 1.73GHz machine) of the lores Mandelbrot set demo:
&lt;ul&gt;
&lt;li&gt;Google Chrome (V8 JavaScript compiler): 25% faster (21s vs. 27s)&lt;/li&gt;
&lt;li&gt;Firefox 3: 14% faster (64s vs. 73s)&lt;/li&gt;
&lt;li&gt;Internet Explorer 8: &amp;lt;1% faster (249s vs. 251s)&lt;/li&gt;
&lt;/ul&gt;
So not a huge win except on faster execution engines. But this is just the first step...
&lt;/p&gt;
&lt;p&gt;
Fixed &lt;code&gt;POKE 216,x&lt;/code&gt; shim to disable &lt;code&gt;ONERR&lt;/code&gt; handler

&lt;p&gt;
Rejiggered internal value storage/passing system to use fundamental JavaScript types instead of &lt;code&gt;{number: value}&lt;/code&gt; or
&lt;code&gt;{string: value}&lt;/code&gt;. I didn't trust JavaScript's type system when I first wrote this code.

&lt;p&gt;
Performance - made &lt;code&gt;GOTO&lt;/code&gt;/&lt;code&gt;GOSUB&lt;/code&gt; not do a linear scan to find the line (d'oh). Significant perf boost for IE.
&lt;/p&gt;
&lt;p&gt;Added Unit Tests sample. Coverage is not complete but it's getting there.&lt;/p&gt;
&lt;p&gt;
&lt;code&gt;RND()&lt;/code&gt; with negative now consistently reseeds (added custom pseudoranom number generator)
&lt;/p&gt;
&lt;p&gt;
&lt;code&gt;FOR I = 10 TO 1 : PRINT I : NEXT&lt;/code&gt; now correctly prints &lt;samp&gt;10&lt;/samp&gt; then finishes (was previously incorrectly inferring &lt;code&gt;STEP -1&lt;/code&gt;)

The ASCII Pac-Man sample was really &lt;em&gt;Unicode&lt;/em&gt; Pac-Man, which the bitmap font doesn't support, so it broke. So I cheated.
