In the original DBP IDE, if you typed something like this:
` do stuff...
x = 5
if x = 5
print "x = 5!"
else
print "x is not 5. :<"
endif
You would see "x is not 5. :<" The reason for this is that "..." is the concatenation string and so it would cause the next line to become part of the comment. (Of course, you can change the concatenation symbol to something else, but it was '...' by default.)
Granted, C++ has the same thing, but it's not "..." Instead, it's the less common occurrence, "\" which is also the escape character anyway. So it makes sense to do so.
Now, if you're wondering why you would even do anything with that to begin with, it's to keep your lines from becoming so long that you have to scroll. It's a common courtesy when sharing code to keep your lines less than 80 columns long. (Nowadays it's more like 120 to 140 columns... But I prefer the 80 column marker as I sometimes do work in the terminal anyway.)

I always assumed you could, but I never looked up how it would be done. (I implicitly assumed it was just a repeated sequence of matrix multiplies, potentially. But, considering matrices are weird anyway, I scrapped that idea early on.)

What does "!" represent in your notation? A quick scan of the link did not provide any obvious meaning. (I only glanced though, so maybe I'm missing it.)
Edit: Found it.

This post should be a palindrome if I didn't take too long to write it...
Edit: Yup! 32,223 <- The
post number (correction) is a palindrome.
