Thank you for this great idea that is worth much more than $.02. :-) I can tell that my problem is completely solved now, much better than I had hoped previously. I am glad to announce this small guide to functions which is the result of my last two day's work: http://hu.wikipedia.org/wiki/Szerkeszt%C5%91:Bin%C3%A1ris/Fixes_and_functions_HOWTO This shows not only an example of a complicated replacement, but also the way to compare the match to the whole article (removing redundant links), or generating a long fix by means of a function. Another example is how to choose between two options for replacement during runtime (when you cannot decide it in coding time without a text environment). -- Bináris
