The interpreter, recursively

This applet creates an interface to a new interpreter. The interface was cooked up rather late in the night ;-) and I will take no blame for the way it looks.

The interpreter interface appears as a separate toplevel window. Note that you need to be on this page when you first use the interpreter, or you will get errors when using the toplevel window.

Using the interface

You enter text in the lower window, click the button, and if the evaluation is successful, the results appears in the top window. To close it, use the File -> Close sequence. Clicking on the Help menu shows various parts of the documentation in the parent browser.

Examples

You should see some statements already present. Hit the Evaluate button to see the results.

Enter this set of statements

Frame top = new Frame;
Button button = new Button;
Add(top, button);
FrameShow(top);

and hit the evaluate button. To make the new frame go away, use this statement

FrameDispose(top);

Here is the source to the script that makes this interface.
