maximum index value of a list variable

Posted on by treddfw

Using the "Read Text from file", I'm storing the contents into a List variable. I simply need to know how many lines the text file contains. Without looping through each index and manually incrementing a LineNum variable, is there a function that would tell me the maximum index value?

Many Thanks!

If you have a list stored as %List%, you can get the number of items in it as %List.Count%.

But if you are looking for that to be your loop max, then you want %List.Count - 1% if your %LoopIndex% is being used to reference the row you are looking for in your list. Because the list is a 0 based index, the first item is 0, the second is 1, so on and so forth until the last item is %List.Count - 1%.

Then, when you need to call that row in the loop, you say:

%List[LoopIndex]%

Good luck!
