wow, don't get too fast, Smidget 
19 was one of the toughest levels before I actually explained what the format is, so consider yourself lucky
and you have to answer it in words
EDIT:
good news for all players stuck on this riddle
I have gone over the entire riddle and made it easier by adding more hints and explanations.
Also got rid of all source hints and replaced them with hidden hints - no need to rammage through that pesky source code any more...
You will feel it mostly in the first half of the riddle, which is now more easier peasier, but still not completely trivial.
The second half still has several challenges left in it, but is also more riddlers friendly now
Hope you enjoy the improved riddle
