You can modify it at will. What I use it for is this:
I put a few thousand urls into a program called GetBot.
it saves a log containing all of the urls it visited and if the download was good or didn't work.
My program takes the log, strips out all the invalid connections, removes the Done, from the line and
writes all of the good stuff to another file. Some of the lines had characters well over 255; so I had an opportunity to use the Istring command. Very Nice!

I had very little experience programming in emergence, but I am feeling much more comfortable with the language now.

Edit 11th, 3:40am EST -- Cleaned up my code a little bit. :)
