Rotate and Scale Mesh Shape

[King Mocker]

Thanks for the praise bplus.

I have a couple of questions coming from making this:

1. Is there a UCASE$ equivalent when using _KEYDOWN, rather than having to specify values for both upper and lower case keys?
2. Can someone suggest a better method for toggling the shape using a single key and without affecting the speed of the main loop? 
    Without the 'framecounter mod' kludge it toggles too fast to be user friendly.
