   > Wyatt, I think David's BASIC code is OK because it's presented as a   
   subroutine and is not intended to run as a stand-alone program. I agree that   
   if you want to exercise the code stand-alone, you would need to either change   
   RETURN to END, or add a line    
   on the front like 10 GOSUB 6000 : END   
      
   It is ***YOUR*** assumption that David's BASIC code is presented as a   
   subroutine. But It does NOT mean that EVERYONE who read his message will get    
   the SAME impression at all.   
      
   I simply mentioned that changing line "6060 RETURN" into "6060 END" will NOT   
   generate error when execute the code. For those who incorporate David's code   
   as part of their BASIC program, they can simply ignore what I suggest.
