Testing a parallel interface today, I managed to type in some incorrect 
code which, on first appearance, shouldn't work BUT DID!  The details of 
the interface are irrelevant, but include a C011.  Spot the deliberate 
mistake in the following code precis:

PROC interface()
  VAL link2.in IS 6 :
  CHAN OF [2048]INT16 from.c011 :
  PLACE from.c011 AT link2.in :

  [2048]INT16 data :
  BOOL running :
 
  SEQ
    running := TRUE
    WHILE running
      from.c011 ! data
:

Prodding around in the interface with an oscilloscope, I found that, lo 
and behold, the c011 was getting an acknowledgement for the data I was 
feeding into it, despite the fact that I didn't have a Transputer 
reading data at the other end of the link.  Yes, it should be
"from.c011 ? data" in there.  Has anyone else come across this rather 
bizarre behaviour?  Have I made a new discovery?  Should I publish?  Am 
I going to be shot down in flames?  All and any thoughts on the subject 
would be much appreciated.
