Actually GrandPa your option won't work.

Your logic is good, but you haven't completely thought it thru... (you still had $8D instead of $80 by the way - but forgetting that)...

Suppose you're dropping in speed... 101, 100, 99 <<< and there's the problem...

The last display was 100, you now shift over by one character postition and you display '99' over the top of the '00' part of 100. You haven't erased the '1' so your display goes...

101, 100, 199, 198 etc etc...

Keith hit it in one... but if you don't want a waving km/h display those first... and then just concentrate on the numbers. You can have leading or trailing blanks then (depending if you want left or right numeric justification).

OK... Keith got there first... *smiles*
