Title: BASIC7 extension
Post by: MIRKOSOFT on July 24, 2009, 09:43 AM
Hi!

I tried to relocate $0302 (read and execute basic line) vector, but really don't know how to end procedure when is my command found.
It's simple when is my command not recognized, only jump to original $0302 vector.
But where to jump when my command recognized is? After executing I need to show prompt "READY."
Can you help me?
Thank you very much.

If you want to see a really good example how to extend BASIC in the C128, read pages 197-201 in Mapping the C128. If you don't have that book you can download it here (http://www.commodore128.org.uk/books/Mapping_the_Commodore_128.pdf).
