and

Code:

EXPORT PROG2()
BEGIN
 PROG1.var1:=PROG1.var1+1;
 RETURN PROG1.var1; 
END;

Run PROG1, then PROG2 and you see that var1 has changed. If you run PROG1 again, it confirms that var1 really has changed. Likewise, you can alter PROG1.var1 from the Home screen as well.

You are correct. One can access a local variable that was created inside a program block by using its fully qualified name. Still, I found Han's explanation of program variables to be better than the explanation in the user manual. There was another exception about variables created in an app view functions, but I can't remember it.
