I had no idea I would get comment SPAM here ! :-O
That sucks.

Anyway – what I was going to write was that C64 Forever v10 has a STELLAR feature. You can CUT and PASTE BASIC code into it ! Amazing !
So when you find that programming PDF with copyable text you can just paste into the Emulator ! Even running the software on Wine !
(On Wine it is unstable. But better than before.)

Downloadable plus – is the way to go ! Upgrade if you have an earlier version.
(I dont know how early.)
