One problem with this pseudo-code is that you seemingly want to start on the same loop at steps 1) and 4). Therefore, it is more a trace of steps than pseudo-code that can be executed (by a pseudo-computer, of course). See if you can rewrite your pseudo-code so that it only needs one loop statement. Questions that will help: 1. What are you matching? Strings? 2. Where do the things you are trying to match reside? An array? Some external data source? 3. Do your actions in step 5) involve one match or a combination of matches? 4. How does finding a match add to the search space (step 6)? 5. What is the output from step 5? -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
