Thanks to everyone who replied, I really appreciate the input.

Special thanks to Tim who emailed me off list as I now have a working device! A
real nice Xmas present for me!

In the end I threw out the idea of using timer0 and the Basic 'Random' command
and followed Tim's advice of using a double nested loop in the 'Main' loop to
produce a 0-1 count and a 1-31 count. These numbers are then used in a delay
loop and an 'A or B' decision line to come up with the desired result. It works
perfectly and the timing is easily adjusted via the multiplication factor in the
subroutine loop.

Oh boy am I now a happy guy as I had worked hard at this considering it was my
first electronics project in many years and my first with a programmable chip. I
just have to get it off the breadboard and into a box now and it will be ready
for field trials.

Thanks again and all the best for whatever festival you follow at this time of
year.

Larry
