Bruce,

Thanks for the reply, looks like I have fallen foul of the curse of high level languages and forgotten all my assembler! I will have to go and brush up I think!:-D

Darrell,

Thanks also, I had seen the ?CB notation in your LCD Bargraphs but couldn't find any reference to it with google. I have now got my macros working nicely, thankyou.

I am guessing that since "everything is just numbers" there is no clever way to tidy it up and automatically detect what you have passed the macro?

Thanks

Andy
