Hello,

I am trying to keep tab of the number of times that a curve passes a certain line but I can't get the counter to work (i++ style).

e.g.:
algorithm
  if  y==constant  then
        i:=i+1
  end if;

This only makes i:=i+1 at the moment when condition is true.. afterwards it reverts to its old value.  How do I change it for good?

Help is much appreciated.
