Francisco, Mathematica thinks (understandably) that you want to divide by 0.1 . If you change your statement to: kk=0: newlist = {1,0,1,0,0,1}/.(1:>++kk) you will get the answer you are looking for. regards, RF >>> Francisco Gutierrez <rpena at impsat.net.co> 01/12/00 07:35AM >>> I have M 4.0, window 95. I have a list of 0's and 1's, and I want the one's to perform a consecutive numeration. For example, transform {1,0,1,0,0,1} into {1,0,2,0,0,3}. The easiest (and most elegant, I think) way to do it is with a counter and rule delayed: list={1,0,1,0,0,1} kk=0; newlist={1,0,1,0,0,1} /.1:>++k However, the answer I get from this operation is completely odd:{10.,0,10.,0,0,10.}:>++k. I closed my session and re-started my computer, but I keep getting the same stuff. I don't understand what is happening. By the way, this problem didn't appear in M3.0. Can somebody help me?
