in reply to Reaped: Pattern matching
Welcome to PM!
To take the sting off the remainder (I hope), we're always glad to see new participants who show a desire to learn and to contribute. You may want to get a handle (ie, register) so you can participate more fully (and perhaps nail the USD 5,000,000 prize for the best question by a newcomer [ sorry, annonymonks are not eligible] ).
But this question is a bit lacking (and you tried to post it to the wrong section). Suggest you read On asking for help, How do I post a question effectively?, Markup in the Monastery, I know what I mean. Why don't you? and Writeup Formatting Tips. Then emend your question in a form that's recommended here (short form hints: include your code, errors, and warnings inside <code>...</code> tags.... ie: show a little effort).
You should also clarify what your para beginning with "question: " actually means.
Sorry, we expect SOPW to seek wisdom, not to ask us to do so for them.
