That's the cool thing about 'each'  - you don't have to do anything
else.  The code inside the do-end block will be called for each line,
with l set to that line.  Try adding 'puts strln' in place of "Now
what".  That will print the whole file.   Then replace the puts with
whatever processing you want to do on each line.
