My Apologies. I was editing my reply. As I mentioned in my previous post

There is no fixed text as I mentioned in the question. It is more about start position or end position. I have these start position or end position as numbers and not text. The text/character at the start position can be a "Space" or a "Full Stop". So I can't find it or am I missing something here?



Thanks again for patiently helping me out Paul.
