Never used an interrupt before in my life, but am going to try in my current project. I need to use the 'interrupt-on-change' capability of the 18F to detect (and hopefully count) the decoded clock output from a rotary encoder. Do you have (or) can you point me to, an example of 'interrupt-on-change' using your routines?

Thanks very much, and I'm waiting to see the unfinished pages on your site, Darrel!
