Ok having run this in real time I have a problem. The variable time is byte, and so the maximum value I can have is 254. But setting the "if time = 254 then goto chase" still gives too short a period before the jump is made. I don't want to use a pause statement as that will cause the program to miss the odd beat whilst its waiting... What is the correct designation I should use for the varible, so I could increase the value to something like "if time = 1000 then goto chase" - is it var WORD ???
