Variable problem

[Pesticida]

Hi
I have a Variable Problem!

I have a Variable DataIn:

Datain VAR Byte [3]
Dummy VAR Byte [3]

now for example i want to use this to compare the bits and to found what bit have change:

For N = 0 to 2
For S = 0 to 7 ' My Bits
If Dummy [N].0[S] <> Datain[N].0[S] Then .......
Next S
Next N

But this is the wrong variable syntax (Unsupported array syntax!)
Thank You for any help
