Some of you guys blow my mind. I eagerly learn from your wealth of knowledge. In the past, modifying the DT_INTS was a simple matter of taking care of Interrupt PIE/PIR locations. At least on the MCUs I've worked with, so far so good. I will look at the data sheet and the DT_INTS-18 ASM to try to learn about what was mentioned in the previous 2 posts and see what I can learn. Thanks so much for your valuable input.

Richard, how were you able to test a PBP INCLUDE on a MCU not offered in PBP3.1? Are you already working with the new K42 using C18 or something, or did you test it in some simulation (like Proteus) package? I reference line 1, "the latest attachment is not working."
