John,
I tried to put this part of the code into my test script without the ping
word and it worked fine. Yes, I uncommented the line that does not work for you.
I'm going to have a closer look at ping...I wonder if it's running out of stack or
doing other generally wierd things...
> :NONAME ProximityDriver ACTIVATE
> STOP
> BEGIN
> PAUSE
> ping
> \ [ HEX ] RCX_POWER 4000 POWER_GET RCX_POWER @ 0= IF STOP THEN \ this STOP is broke
> AGAIN
> ; EXECUTE
I also checked into EMIT - it's only blocking because of the stupid IR tower. I have
to be sure that it echoes back the character I just sent, so I don't get confused
between a character I'm expecting (from the tower) or one that I'm not (from the user)
Maybe it's time for a word that unconditionally bangs things out the IR port?
This IS more fun!
Cheers,

| Here it is, it is working, but is waiting for IR_MODE_HI, STOP and a non-blocking EMIT. There is a light sensor on the centre connector pad. .dp displays proximity in the LCD as DEFCON.RawLight alternating with the average ambient raw light sensor (...)
