Testing a PiXCL source file
Once you have written your PiXCL application code, you need to test it with
the interpreter to verify the correct syntax and operation. You must have saved
the file first. The default file extension is .PXL.
Click the button or select the Test Script menu item. A dialog box is
displayed telling you the name of the PiXCL script, and an OK or Cancel button. Click
OK to run the program, or Cancel to return to the editor.
