Hello,

I see in the Beta demo programs a lot of lines where hard coded numeric
values exist:

	 clear : (# exit 6 #);
   exit 130 #);                  (* resource id's for edit menu *)
  
   windowId : (# exit 128 #);    (* resource id of the application window
*)
   do (100, 100) -> position;
   (300, 300) -> size;

Now in a real world application these numbers would exist in a separate
<Defines> file and they would be reference by some constant name, or they
would be calculated based upon some environmental setting.

This is accomplished in C with <#defines> so the above would be:
#define  H_WINDOW 100
...
 do (H_WINDOW, V_WINDOW) -> position;
   (WINDOW_WIDTH, WINDOW_HEIGHT) -> size;
etc.

What method in Beta would you use to replace all hard coded numeric
values with substitute <macro> values?
