[maxmsp] Re: Comparing current value and previous value in a list

I am not sure if you want to compare two consecutive numbers or all numbers of your list with the current one... comparing two numbers is easy (see patch), also the biggest number out of a list isn't that hard (patch again) - I am sure there is a more efficient way, but it's late... 
Hope this helps and gets you started.
