Subject: Re: Is the key delaying interpretation of a variable?

Thank you so much for your response. I had tried Marcin's suggestion,
but
got error messages.

I have been wondering what to do, and then I saw your suggestion from
last
week, and suddenly what you were saying clicked!

> If you insist on using a global
That's it! In the original program, $shoulder is a global so various
parts of the
program can access it. It holds the memory of the system.

Having rewritten the program an OOP way, this is no longer necessary.
The object holds the memory of the system! So I changed the keyboard
proc to say

keyboard = Proc.new {|key, x, y|
   case  (key)
      when 's'[0]
         upperarm.rotation[0] = (upperarm.rotation[0] + 5) % 360;
         GLUT.PostRedisplay();

and now it all works fine. I hadn't really understood what the keyboard
proc was doing! 

Thank you!!! I can move on again! wonderful.
