Identification of the first element of a 1-D array

[asa]

Hello.I am collecting a continuous data(1-D array)into a while loop and I would like to extract the first element, when I use the index array(index 0)I have a variable value, is this maybe because the data is continuos??Could somebody help me, thanks in advance, Asahel

How are you building up the continous array inside the while loop? Is it possible that you are appending the new data at the beginning? Is it possible that the new data replaces the old array data?

Could you attach a simple example of what you are doing?
