-  About assembler usage:
-  ----------------------
-  I used as few as possible assembler to allow an easy port
-  to other processors. Today, I think it's wasted time to write
-  assembler because different versions of a family of processors
-  need different implementations.
-
-  To improve performance, I changed all integer arguments and
-  functions results to longint, because 16 bit instructions are
-  lethal for a modern intel processor.
