PIC18 interrupt handler, where to save W etc?

[Bruce]

I'll take that as a NO.

Yep. I don't see any reason to even have priority levels enabled unless you have one interrupt that needs to interrupt another. I should have said NO priority levels VS LOW priority...

My point was just to let the OP know he didn't need to enable priority interrupts, or use a high pri interrupt just to use the fast return with auto context restore because this;

One nice thing about 18F's is that you don't have to save W, BSR and STATUS when using High Priority Interrupts.

Made it sound like he did.
