   About 40% of the operating system is now written in C, 30% in both MACRO-21   
   and BLISS.   
      
   Work was done in the mid-90's to make it easier to write kernel mode code in C;   
   most of the MACRO-only JSB interfaces were jacketed with the ability to call   
   them from C.   
      
   As a result, the "Writing OpenVMS Alpha Device Drivers in C" book (Szubowicz,   
   Sherlock)   
   describes some of those changes.
