I had no spare tapes to save my work so I had to take a picture! The program started out in the usual style as a "Hello World" program. I then hacked around and changed a few bits and eventually ended up with the above.
So what does it do? - well THIS:
Yes I know its simple, egotistic and self promoting, but I don't care. The amount of enjoyment I got from doing that is huge. 20 years ago when I wrote a program for the first time I could save it on a cassette tape. Where on earth am I going to find one of them in 2013???
I have found some good resources online that helped a lot when building this program.
A list of memory address that can POKEd
An e-book about an awesome line of code!
A wiki page detailing the VERBS in the version of basic installed on the commodore
An online version of the C64 Manual
