My point, which was obviously not well made (twice!), was that given the minimal requirement > >>>> I need only OMS.FD.08.03.000 this much part of the string. a sort of Reductio ad absurdum argument leads to a solution of > >>> $_ = "OMS.FD.08.03.000"; As such I should probably have given the solution last on my list, but that would have entailed applying some sort of likeliness ordering on the list, which I didn't really feel like doing. In any case, perhaps Irfan would like to clarify his intent and let us know which particular parts of the problem are causing him problems? > Sure - the problem was understated, but all of your solutions modified > the object string when a simple regex with a capture could have provided > a solution with no side effects. > > An analyst's job is to establish the problem as well as the solution, > not to invent possible problems. You are correct. My re-reading of the original post still suggests that modifying the string is the most likely requirement, but that's hardly important any more. And both of us have wasted too much time on this already, for which I apologise.
