John, I think you've missed my point. I'm currently 'exploding' by ',' to give me sub ranges and then 'exploding' the subtranges by '-' to get the actual start and end, adding the subtotals up for the page count. The problem is that I want to be able to replace the different types of '-' that can come through, without knowing what they might be using.
In short I'm looking to search for any character that is NOT one of the following: "0-9 cdilmvx ," and replace it with '-' [chr(45)] (I do an initial strip of spaces at the beginning of the process).
