I'm pretty sure I've seen the solution to this before, but, typically, I can't remember it. I'd like to convert this:
abc 123 45 6789 0 wxyz 98 333 44 8765 to this: abc 123 abc 45 abc 6789 abc 0 wxyz 98 wxyz 333 wxyz 44 wxyz 8765 The length of the "prefix" would/could be specified, so it wouldn't have to be deduced in any way. Also, the non-prefix "words" in each line could be assumed to be the same length: abc 123 45 6789 0 wxyz 98 333 44 8765 Thanks for any suggestions. - mb
