Just need to clarify...

Al, closer but not there yet. Sorry for the delay, I had to adjust your code to invert the Collumn port for this display. Bruce I haven't tested yours yet but I had started in that direction.

Bitgenerator:
Bvar=-0
random Ran_Word
Avar= Ran_Word.byte0
if Avar.0=1 then Bvar=Bvar+1
if Avar.1=1 then Bvar=Bvar+2
if Avar.2=1 then Bvar=Bvar+4 ;isolate a random number 0to7
Cvar=1
Cvar=Cvar<<Bvar ;set a single bit in the byte
Cvar=Cvar^$FF ;invert for a low on one bit
rcol=Cvar ;set port
Bvar=0
random Ran_Word
Avar= Ran_Word.byte0
if Avar.0=1 then Bvar=Bvar+1
if Avar.1=1 then Bvar=Bvar+2
if Avar.2=1 then Bvar=Bvar+4
Cvar=1
Cvar=Cvar<<Bvar
Row=Cvar
pause 100
goto Bitgenerator

(Wierd: code tag nor the editor would accept << in the code)


this method works (sorry you can't see all the code) but gives some repetition in general pattern on the diagonal. I will use the DCD. I'm still trying to understand Al's "Ran_Word.0[AA0 + 8]" . What is this doing to the PortC.0[AA0], is it resetting to a number less than 8?
thanks guys, I'll have to chew on this for a while.

I have 2 suggestions:

Taz, try to put a meaningful title to your thread; like REPEAT-UNTIL or something.

Mountain, you're always best to start a new thread when you have a new question (since this thread is about REPEAT UNTIL syntax).

It may not seem like much but it makes things so much easier to find stuff when you look at the list of threads.

Robert, thanks for the suggestions.
