The text area below (<b>source</b>) works like a Smalltalk workspace:
<bl><li>
To evaluate some code, just select it and press the <input type=button value="do it" onClick="doIt()"> button.
</li><li>
Pressing <input type=button value="do it" onClick="doIt()"> without a selection evaluates the line that the cursor is on.
</li><li>
<input type=button value="print it" onClick="printIt()"> is like <input type=button value="do it" onClick="doIt()">,
but it also prints the result.
</li></bl>
Also, you can press <input type=button value="save it" onClick="saveIt()"> to save the current project.
