The SubL Interactor is an input window for evaluating SubL expressions.
To evaluate an expression, simply enter the expression in the window and press the [Eval] button. This will bring up a new frame which contains the last form (the expression just evaluated), the results of the evaluation, and a fresh input window. If the expression is malformed an error message is returned.
To get constant completion while typing in an expression, press the [Complete] button in the middle of a constant name. As always, possible completions (if there is more than one) will be displayed in a separate completion window which will be reused for future completions. Completion is case sensitive, and requires that JavaScript is enabled in your browser.
To completely refresh the input window and start over, press the [Clear] button.
To return to the previous frame, press the [Back] button.
