So I guess what you're saying I should do is...

1: Cut the substrings from the main NSString at the calculated offsets
2: Stick the sub strings into an NSArray
3: Sort the Array
Correct?

That should do it. One last thing I need to so is convert the string values
into Numerical values. What is the Cocoa equivilant to the older toolbox call
StringToNum()?
