in thread CPAN shell - passing params for module installation

I'm trying to work out how this is doing what it is doing. I don't understand the $- as I thought that had to do with lines left on a page for formats and writes. Please let me in on the secret.

Cheers,

    Correct. But you can assign to $- e.g. to acommodate the page length for your clay tablet printer 1. $- is 0 by default.

    The rest is easy - ord(R) == ord(E)+13, the other chars are offset -1 to the output (S,E,L -> T,F,M).

    German ESEL is English DONKEY, which is why I made that up in the first place. So the thingy is only acceptable with a smiley appended... ;-)

      Right, got it now! Thanks for the explanation. I might even have got the ESEL/DONKEY joke if my German school studies were not 30+ years in the past.
