Yes, you can use the libraryStack handler to initialize your globals 
in your library stack.

on libraryStack
   global myHalfCircle
   put 180 into myHalfCirle
end libraryStack

The libraryStack message is sent when you call "start using" for your 
library stack, so is well suited for this purpose.

Of course, you still need to connect to those globals in each handler 
that uses them by including, for example,

   global myHalfCircle
