We have created a test container for you to test your scripts without the need for you to create a separate program.  It is an MDI application, allowing you to open as many script windows a you want.  Each script window is divided into two parts.  The top is where you enter your script code, and the bottom is where you can view output, if desired.  You can choose to view output as either HTML, Plain (or RTF) text, or none (in cases where the output is binary).

Please refer to the screenshot below.  This script reads a database to generate an XML document.  Notice the output at the lower half.

The Test Container actually creates a ScriptObject and uses it to execute the script code, and display the output in the specified window.  Since the output is XML, the selected output window is Text.  If we were generating an HTML page, we would select the HTML output window.
