A = A(0)

[Dimster]

Thanks very much for this feed back... So they are two different variables (actually a variable and an array) which appear to have the same name    ie -- Event10 = 3124, Event10(0) = 598. I could use one as a temporary hold of a past value for comparison with the present value of Event10. 

But I gather, something like Event10Present = 3124, Event10Past = 598 is more the accepted practice because to the overhead associated with arrays?
