        At the time this report is printed, two bugs are  puzzling  me  but
time does not allow me to take a closer look at them :

<----------------
        1) The motion queue management suffers a flaw that should be  fixed
in  the  coming weeks.  At the time a motion is entered into the queue, the
'queue' function is called.  It returns a  pointer  to  an  allocated  area
where  the  new data is stored.  Before the data is installed, the setpoint
process may well look into the queue an obtain an incomplete record.
 <---------------
		Fixed


        2) The high  speed  fifo  interface  caused  some  synchronizations
problems  that  were believed to be solved.  It turns out however that when
the function 1 called by the real time interface take too long to  execute,
a  system  crash  may  occur.  I got around that by not using function 1 in
RCCL although it's a pity and by warning the other users.

	There are also many things that would need to be reworked.
