I suppose that could be true. The OP only asked a question after all. It's entirely possible daniel99 did not want an answer to the question but would be grateful for just a reminder that awk exists; a2p while we're on it. And it seems possible he is 18, going on 19, years of age which, as you rightly point out, means he was not born yesterday, strengthening your case. Lord knows most of the monks here do not like to see or compare or discuss or learn about code so withholding it is an act of humanitarianism, I understand. Let them eat fish!

For my part, if someone says something is “very simple” it is less assumption and more reasonable that put up or shut up is a fair rejoinder. And to continue to be fair, translation of concepts into “actual Perl source-code” can only ever possibly be left as an exercise for others by someone who knows no Perl. I keep saying bloviate lately. It's wearing. Maybe I might finally get a neologism to stick, boviate.
