Hallo Benny!   
      
    BP> my consern is more or less does it allow to write new bios ? :)   
      
   I haven't checked.  So far all I have done with it is to bootstrap in a pure   
   64-bit enviroment and get it to compile the supplied ./examples/hello.bas.    
   None of that required any jiggery-pokery with the bios.   
      
    BP> i think its possible not all basic commands that are implemented   
    BP> in freebasic ?   
      
   I believe the opposite might be true; that more basic commands are implemented   
   than the garden variety basics, given the different the claim, "You don't need   
   to learn much new if you are familiar with any Microsoft-BASIC variant.",   
   posted on the home site https://www.freebasic.net/ as well as the -lang switch   
   which is worthy of investigation if you are concerned about compatitility.   
      
    BP> i remember only qbasic from my old time when i got a wife :)   
      
   I never used it even when I had a wife.  I used gwbasic way back when but only   
   a couple times to suit a onetime solution.  However gwbasic is an interpreter   
   and not a compiler but I am guessing the syntax is somewhat similar.  That was   
   30-ish years ago so I can't be sure but I am sure that it wasn't running on a   
   commodore.   
      
   Het leven is goed,
