That's OK, just beware that the way you've done it you've modified the
string which was passed in. e.g.

a="foobar"
copy_ticket(a, "/tmp", "E123", "x", "y", "z")
puts a

will print "foobar.txt"

To avoid that:

   filename = filename + EXT

(which creates a new String object, and then updates the local variable
'filename' to point to this new object)

This is an interesting "small" file-chomping task. I wonder what the
equivalent Java program would look like :-)
