I modified it to run on my LCD and it counts from 1000 to 1012 by adding two, then does it all over again.

So the first loop is WRITING the count to memory and the second is READING and displaying from memory to the LCD. B1 being the high BITS of the BYTE that make up W2 and B1+1 the low bits of W2, is that right?

So to complete our 'mission' should I try and do the same and use a loop or assign BYTES to a WORD (if that makes sense).
