   Very readable. But not obvious to come up with.   
      
   But it got me curious.   
      
   I consider it a given that the age distribution for competent Bliss   
   programmers are a bit "right side heavy".   
      
   VSI (and Oracle Rdb team for that matter!) has a lot of Bliss to   
   maintain.   
      
   Do you have a plan for how to train new Bliss programmers?   
      
   Very few example on the internet. No books that I are aware   
   of. Not any active forums.   
      
   Not easy for anyone to learn by themselves.
