        The text area below (<b>source</b>) works like a Smalltalk workspace:

        Pressing <input type=button value="do it" onClick="doIt()"> without a selection evaluates the line that the cursor is on.

        <input type=button value="print it" onClick="printIt()"> is like <input type=button value="do it" onClick="doIt()">,
