That is one hell of a page! Id like to link to it from my techref's pic
page, ok?

For some constructive criticism, that page desperately needs to be
organized. Want some help?

James,

The 18c series are the first PICs to have instructions that are > 1 word
long, hence it's possible to bypass the first word of the instruction
and execute the second on this family.

As much as I hate quoting continually from a single source, the most
reasonable argument of C/Asm can be found at:

I particularly like points 5a and 5b.
