another good example is searching through paragraphs (below), which contain some combination of keywords. here the important part is ~(_*\n\n_*), or “does not contain two consecutive newlines”, in other words, the boundary of a paragraph, so it matches paragraphs! then you can combine it with any other regex to find paragraphs that contain certain keywords, but not others. this is very hard to do with traditional regexes without writing a complex and fragile pattern that tries to match the entire paragraph structure.

The implementation of this doesn’t really make any of this clearer, but there were a few handy tricks I was able to use while working through it. One of them was that I didn’t need to record anywhere whether we were pushing the button in or releasing it; we could deduce that from the last value we wrote in step 4. Another was in step 6; the N*8 term has a maximum value of 200, which means that we can put that result in an index register and do all our copying by indexing from a base of $2008 or $2009 as needed. No explicit pointers were necessary at all.
