After reading the documentation, i added the slice opperator in one
place, the one it was strictly necessary to the design to modift the
list, and in the others (with the cdw) i simply restrained myself as i
didn't NEED to modify it, and the program functioned exactly as
expected.

Thanks newsgroup. (btw: this was one of my first real coding effort
spaned from gtting pissed at having to open 18 instances of notpad to do
a simple task.)

And though it does not sho precisely why, i can understand how a loop,
iterating on indexing pointer would get confuzed as the list items
change places after a delete..
