Re: How do I re-use a procedure?

I'm guessing you're using the IDE here, but it doesn't really matter.

What has happened is that the place you are calling the procedure from is 
higher in the source code than the place it is declared. Euphoria only looks 
up for procedures, not further down. What I suggest you do to fix this is to 
replace the Print_to_Screen call with:

invokeHandler(MenuP_Scn, w32HClick)

This takes care of any code location issues, and is more robust, cause if 
you change the name "Print_to_Screen" to something else, you don't have to 
change the above call.
